The basics

What are the differences between MediaWiki, Wikimedia, Wikipedia, and wiki?

Please see Differences between Wikipedia, Wikimedia, MediaWiki, and wiki for a detailed answer.

I want to use a MediaWiki instance to (blank). Am I allowed to?

MediaWiki is free software: this means that you may use it for any purpose without legal hindrance. Furthermore, its licensing conditions apply solely to the software itself. This means that although many wikis license their content under a permissive license, you are not obliged to license the content submitted to your wiki in any particular way. Of course, as a project founded to support sites like Wikipedia, we encourage you to license the texts you write under a free license, but, in short, you are not required to.

If you wish to alter or amend the software itself, in general, you are permitted to, but there are some restrictions and you should consult the full text of the GNU GPL version 2 for details. Because MediaWiki is provided free of charge, there is no warranty, to the extent permitted by applicable law.

How do I create a wiki?

Creating a wiki implies installing MediaWiki on a server and having access to manage it. There are different options, depending on your level of expertise:

  • To create a wiki on your own server, follow the Installation guide.
  • Some hosts offer one-click installs, or allow creating a wiki on-request. See Hosting services for different options.

This site (MediaWiki.org) or the Wikimedia Foundation does not allow individuals to create wikis.

Enjaçament e conformes

Ont pòdi joscargar MediaWiki ?

Download the latest stable release of MediaWiki. Files are supplied in a .tar.gz archive. MediaWiki peut aussi être obtenu directement à partir de notre référentiel Git.

Consi pòdi enjaçar MediaWiki ?

Installer MediaWiki prend entre 10 et 30 minutes (lorsqu'on utilise MySQL), et implique de télécharger/copier des fichiers, créer une base de données et un utilisateur, et exécuter le script d'installation pour configurer le logiciel. See Manual:Guida d'installacion , where you will also find the minimum system requirements.

Comment puis-je installer MediaWiki en utilisant un package ?

Bien qu'il existe des packages (par exemple Debian, RPM, etc.) disponibles pour installer MediaWiki sous un système d'exploitation Linux/Unix. The MediaWiki development team refers you to your Linux distribution for assistance with installing, configuring or using them. Les communautés individuelles qui maintiennent de tels packages fourniront normalement le support et la documentation.

Be warned that third-party distributions may be older versions, so pay close attention to compatibility information for directions and extensions.

See also: Software bundles

Puis-je installer plus d'un wiki sur un serveur en utilisant MediaWiki ?

Il est possible d'installer plus d'un wiki sur un serveur tant que :

  • You install multiple instances of MediaWiki (such as with a software bundle like the Bitnami MediaWiki Stack); in different directories – one for each wiki

Or

  • Vous utilisez une base de données différente pour chaque wiki

OU

  • Vous utilisez un préfixe de base de données différent pour chaque wiki. If you want to use the same LocalSettings.php file for both, you must ensure $wgServer is dynamically set to the correct value.

Pour plus d'information sur ces options, voir $wgDBname et $wgDBprefix respectivement.

Pour plus d'informations sur la configuration d'une famille de wikis, voir Manual:Wiki family .

How do I install an existing wiki, like Wikipedia or Wiktionary?

The main (but not necessarily the easiest) method is to import. See Wiki importing, below.

(Non-MediaWiki methods, such as Xowa and Kiwix can be found at w:Wikipedia:Database download).

Does MediaWiki require shell access?

Shell access (SSH) is not required for installing MediaWiki, but it is highly recommended. Without shell access, it may even be difficult for you to get a backup of your wiki, or to upgrade to a new version. Some maintenance tasks are not possible at all without shell access. Many major extensions work best with shell access.

How do I install extensions?

See Manual:Extensions for information about installing and writing extensions. See Categoria:Extensions to find existing extensions.

How do I add extra namespaces?

See Creating a custom namespace.

Comment puis-je permettre le téléchargement ?

Les téléchargements de fichiers sont une fonctionnalité de MediaWiki souvent utilisée, mais est désactivée par défaut dans toutes les versions finales actuelles. Pour les autoriser, faites d'abord un répertoire de téléchargement (par défaut images) dans lequel le serveur web a l'autorisation d'écrire (CHMOD 777 ou permettre à l'utilisateur Apache d'écrire dans celui-ci, etc.) et ensuite configurez $wgEnableUploads à true dans votre LocalSettings.php. If you get a "failed to mkdir" error when you try to upload, it probably means that there's a permissions problem.

See also: Manual:Configuring file uploads

Comment puis-je permettre le téléchargement d'autres formats de fichier ?

MediaWiki demande à ce que les formats de fichier téléchargeables soient spécifiés en utilisant la directive de configuration $wgFileExtensions . Usually this directive is situated in LocalSettings.php in the root of your MediaWiki installation.

Par exemple, pour permettre de télécharger des fichiers PDF, ajoutez la ligne suivante dans LocalSettings.php : 

$wgFileExtensions[] = 'pdf';

To extend uploading to more than one type of file, use the following syntax 

$wgFileExtensions = array_merge( $wgFileExtensions, [ 'pdf', 'txt', 'mp3' ] );
See also: Manual:Configuring file uploads

How do I enable embedded math formulas?

MediaWiki allows embedded math formulas. See Extension:Math for complete setup instructions.

How do I set the timezone for my MediaWiki?

See Manual:Timezone

Comment purger le cache d'une page

Pour purger le cache d'une page, ajoutez &action=purge à la fin de l'url de la page.

Par exemple https://www.mediawiki.org/w/index.php?title=Main_Page&action=purge

Or ?action=purge to the end of the page's short form URL:

E.g. https://www.mediawiki.org/wiki/Main_Page?action=purge

See also: Manual:Purge , Manual:Parameters to index.php

How do I completely disable caching?

Add in your LocalSettings.php file the following lines:

$wgParserCacheType = CACHE_NONE; $wgCachePages = false;

"File is corrupt or has an invalid extension"

Some users have reported that after adding a file format to the allowed extensions list, an error is encountered. The text of the error is similar to the following:

The file is corrupt or has an incorrect extension. Please check the file and upload again.

As a possible solution, set the value of $wgMimeDetectorCommand . Under Unix or Linux, this would be 

$wgMimeDetectorCommand = "file --brief --mime";
See also: Manual:MIME type detection

Initial user was not created by installer or it is not an administrator

Sometimes, the installer fails to create the default user, or the user table is lost for some reason. There are a couple of options for solving this:

maintenance/createAndPromote.php

Append --bureaucrat to command line if you want that user to become a bureaucrat, in addition to becoming an administrator.

This will create a new user and promote them to an administrator. For help, run the script with the parameter --help.

Alter the database

  • Execute the following SQL statement against the database:
    • INSERT INTO user_groups ( ug_user, ug_group ) VALUES ( <id>, 'bureaucrat' ), ( <id>, 'sysop' );
<id> above should be replaced with the appropriate user ID which you can see on the user's preference page.
Note: if $wgDBprefix is defined in LocalSettings.php, prepend its value to the table name. For example, if $wgDBprefix is "XYZ", then the table name to use is XYZuser_groups

Temporarily let everyone assign rights to promote your initial user

  Warning: You should not let outsiders access your wiki while you do this, if you use this method. This method may leave your wiki temporarily vulnerable to attack while you do the procedure.

This method essentially involves letting all users temporarily modify user permissions in order to promote one user

Be logged in using that account.

  • Add the following line to the bottom of LocalSettings.php
    • $wgGroupPermissions['user']['userrights'] = true;
  • Go to special:userrights and add the user you just created to the Administrator and Bureaucrat groups.
  • Remove the $wgGroupPermissions['user']['userrights'] = true; line from your LocalSettings.php.

This step is very important, as until you remove it anyone can alter permissions, which is bad.

How do I reset a user's MediaWiki password?

See Manual:Resetting passwords
See Manual:Interwiki

How do I make my base URLs shorter?

(i.e. /wiki/Article_Name as opposed to /w/index.php?title=Article_Name)

See Manual:Short URL

How do I organize pages into subdirectories like /wiki/subdir/PageName?

See Manual:$wgNamespacesWithSubpages e Help:Subpages

Is downloading and using all of MediaWiki.org free?

Yes, it is free in the sense of Free software. See Project:Copyrights for licensing issues regarding the written content of this site.

How do I administrate/manage user rights?

See Manual:User rights for general information. See Manual:Preventing access for methods and strategies for restricting access.

Comment empêcher l'édition par les utilisateurs anonymes ?

Ces permissions sont contrôlées par l'option de configuration $wgGroupPermissions . Edit LocalSettings.php and add the line: 

$wgGroupPermissions['*']['edit'] = false;

If you use Extension:AbuseFilter , any admin can also disable IP editing temporarily as needed.

See also: Preventing access , Manual:User rights

How do I stop anonymous users from reading any page?

  • Add this to the bottom of LocalSettings.php:
$wgGroupPermissions['*']['read'] = false;

See also Manual:$wgWhitelistRead . See Manual:Preventing access#Restrict viewing of all pages for more information.

How do I restrict account creation?

  • Add this to the bottom of LocalSettings.php:
$wgGroupPermissions['*']['createaccount'] = false;

See Manual:Preventing access#Restrict account creation for more information.

How do I require an email address be specified at registration?

See Manual:$wgEmailConfirmToEdit

How do I put MediaWiki into Read Only mode?

MediaWiki version:
≥ 1.5
See Manual:$wgReadOnly

How do I change default user preferences?

MediaWiki version:
≥ 1.4

The MediaWiki default user preferences are in MainConfigSchema.php Don't edit that file, just use it for reference.

Say if you want to hide minor edits in recent changes by default. DefaultSettings.php says: 

public const DefaultUserOptions = [
        ...
	'hideminor' => 0,
        ...
]

To change the preference, put this in your LocalSettings.php: 

$wgDefaultUserOptions["hideminor"] = 1;

To change the default namespaces to be searched, in any version of MediaWiki, set $wgNamespacesToBeSearchedDefault in LocalSettings.php to an array mapping namespace indexes to boolean values. For example, to search the main namespace and the category namespace, use: 

$wgNamespacesToBeSearchedDefault = [
    NS_MAIN => true,
    NS_CATEGORY => true,
];

In some cases, after you change a default user preference, you may also want to change the user preferences of all existing user accounts.

If so, use the userOptions.php script in the maintenance directory. Use the --dry option for the first run, assess the impact and go from there. (--dry does not write the database.) 

php userOptions.php --dry --nowarn hideminor --old 0 --new 1

Also, always backup your database before making these kinds of changes (you do not need to if you are just using --dry).

Moving

Is it possible to move my wiki to a different machine?

Yes. It should be. In essence, you will be backing up your old installation and then "restoring" it onto the new machine. Finally, you will have to make additional modifications to update the wiki configuration so that everything points to the new location.

How do I move my wiki to a different server?

Follow the instructions at Manual:Moving a wiki .

Changer l'interface

Comment puis-je changer le logo ?

  Caution: Do not simply overwrite the default logo installed within MediaWiki (/resources/assets/wiki.png); this file will be overwritten when you upgrade the software.
A larger size can be used by modifying the site’s CSS, but MediaWiki will not resize a logo that is too large. Instead, only part of the image (specifically the upper left-hand corner) will be displayed, and if this corner is white, it may seem like the image is not displaying.
l'image du logo doit avoir une taille de 135 pixels de côté.

The maximum logo size in the Vector skin is ~160 × 160px, while in MonoBook it’s ~155 × 155px.

Le logo du site visible en haut à gauche de chaque page est déterminé par le préfixe de configuration $wgLogos inclus dans le fichier LocalSettings.php . MediaWiki installations prior to MediaWiki 1.35.0, used $wgLogo .

There are two ways to change the logo:

  1. Vous pouvez télécharger un fichier sur votre wiki et utiliser son adresse (ce qui permettra de plus facilement modifier le logo ou le protéger)
    Then add the $wgLogos line to LocalSettings.php, for example:
    $wgLogos = "{$wgUploadPath}/6/62/mylogo.png";
  2. ou utiliser une image téléchargée sur votre serveur par d'autres moyens.
    Add the $wgLogo line to LocalSettings.php, for example:
    $wgLogos = "{$wgScriptPath}/mylogo.jpg";
    (In this example, the image is in the same folder as the LocalSettings.php file.)

If you only want to change the logo on specific pages, override #p-logo CSS's background-image property or use a third-party extension like Extension:LogoFunctions .

How do I edit the wiki's CSS?

You shouldn't edit the CSS files (such as common.css) directly, because it will make upgrading harder if you need to apply your customizations each time you upgrade the software. Instead you need to edit a wiki page called MediaWiki:Common.css if you want to apply your CSS changes for all skins, or a wiki page called MediaWiki:Vector.css if you want to apply the customizations only for the Vector skin.

The content of the MediaWiki:Common.css and MediaWiki:Vector.css pages always overrides the default CSS styles specified in the skin files.

How do I hide the left vertical navigation toolbar?

In other words, how do you make the main content div take up 100% of the display, hiding the logo, toolbox, navigation and search engine?

To hide it permanently, copy and paste the following into the MediaWiki:Common.css page: 

#column-content { margin: 0 0 .6em 0; }
#content { margin: 2.8em 0 0 0; }
#p-logo, .generated-sidebar, #p-lang, #p-tb, #p-search { display:none; }
#p-cactions { left: .1em; }

To instead hide the toolbar when the user presses F11, enter this in your wiki's MediaWiki:Common.js: 

document.onkeydown = function( e ) {
	if( e == null ) e = event
	if( testKey( e, 122 ) ) { //F11
		appendCSS('#column-content {margin: 0 0 .6em 0;} #content {margin: 2.8em 0 0 0;} #p-logo, .generated-sidebar, #p-lang, #p-tb, #p-search {display:none;} #p-cactions {left: .1em;} #footer {display:none;}');
		return false;
	}
}

function testKey( e, intKeyCode ) {
	if( window.createPopup )
		return e.keyCode == intKeyCode
	else
		return e.which == intKeyCode
}

How do I hide the categories at the bottom of each page?

You can hide display of the categories on each page by modifying your MediaWiki:Common.css and adding: 

.catlinks { display: none; }

By default, clicking the site-logo takes you to the main site-page. If you want to change which internal site-page is the "main" site-page, edit MediaWiki:Mainpage.

To make the link of the site-logo link externally to any other arbitrary URL, you can use jQuery code within MediaWiki:Common.js: 

$("a.mw-wiki-logo").attr("href", "http://www.example.com");
$("a.mw-wiki-logo").attr("title", "Go to example.com website");

How do I change the icon in the browser's address line (favicon)?

  • Simply upload your favicon.ico to the root of your domain/subdomain, make sure file name is in lower case and its name is favicon.ico
  • Alternatively edit the $wgFavicon setting in LocalSettings.php and add

$wgFavicon = "$wgScriptPath/path/to/your/favicon.ico";

See Manual:$wgFavicon for more details.

Tip: The favicon image should be either 16 x 16 pixels or 32 x 32 pixels.

Rewrite Rule

If you are using a rewrite rule in .htaccess to remove "index.php" from the URL, you will also need to add an exception for .ico files. Simply add the following rule to your .htaccess: 

RewriteRule .*\.ico$ - [L]

This rule must appear before the index.php rule.

Case sensitivity

When uploading the favicon file, be sure the filename is in lowercase. (That is, "favicon.ico", not "Favicon.ico".) A lot of servers (e.g., those on UNIX-like operating systems) will not be able to find the file unless its name is in lowercase.

Comment puis-je personnaliser la barre de navigation ?

Le contenu de la barre de navigation qui apparaît à gauche de chaque page (lorsqu'on utilise le skin par défaut Monobook) est déterminé par la page MediaWiki:Sidebar. For information on customising these, please see Manual:Interface/Sidebar .

How do I put a text message (sitenotice) on every page?

Put a text in the MediaWiki:Sitenotice page. It will be displayed on top of every article page.

You can also add text to MediaWiki:Anonnotice to create a message that only displays for logged-out users. It is often a good idea to transclude the site notice on the anon notice to make sure that logged-out users still get the information on the site notice.

Comment puis-je changer la page d'accueil ?

Par défaut, MediaWiki montre une page avec le titre Main Page et donne celle-ci comme page par défaut. Ceci peut être changé en modifiant MediaWiki:Mainpage pour pointer vers un autre titre. If this does not change the 'Main Page' link included on the sidebar at install time, edit MediaWiki:Sidebar .

How do I change the Main Page title?

Simply click on the "Move" tab, and move the page to the desired page title.

Usually you also want to change which page is the configured as "main page".

How do I hide the main page title?

MediaWiki 1.38+

The displayed title of the main page can be changed using the MediaWiki messages MediaWiki:mainpage-title and MediaWiki:mainpage-title-loggedin (for logged-out and logged-in users respectively). The main page title can be hidden by setting both messages to empty (or only either of them if the title should still be displayed to logged-out or logged-in users).

MediaWiki 1.37 and below

  Warning: This is not the recommended way to do this for Wikimedia projects as it may cause integration problems with extensions, gadgets and skins.

MediaWiki does not have a built-in option to hide the main page title (see task T8129), but you can use CSS to hide the title. Alternatively, you can use the NoTitle extension.

Add the following to MediaWiki:Common.css on your wiki: 

body.page-Main_Page.action-view h1.firstHeading, body.page-Main_Page.action-submit h1.firstHeading { display: none; }

If your main page uses a localized name or you have renamed the main page you need to change the page-Main_Page part. You can find a correct parameter by viewing HTML source of the main page and searching for the body tag.

For example, if your language is Lojban, the body tag looks like this: 

<body class="mediawiki ltr sitedir-ltr ns-4 ns-subject page-uikipedi_as_ralju skin-vector action-view">

Therefore you should put this line in your MediaWiki:Common.css instead: 

body.page-uikipedi_as_ralju.action-view h1.firstHeading, body.page-uikipedi_as_ralju.action-submit h1.firstHeading { display: none; }

If you would like to hide the title of a "Main Page" in a specific namespace like "Help:Main_Page" add the following to MediaWiki:Common.css on your wiki: 

body.page-Help_Main_Page.action-view h1.firstHeading, body.page-Help_Main_Page.action-submit h1.firstHeading { display: none; }

Note the difference: body.page-Help_Main_Page in comparison to body.page-Help:Main_Page. The latter will not work.

If this doesn't work, you may be using a skin that doesn't support this, or you moved your main page without updating MediaWiki:Mainpage, or you have a really old MediaWiki version.

If the skin uses a different element for the title than a h1 element with class firstHeading, you'll need to find the appropriate CSS selector to apply for that skin.

Comment puis-je cacher la table des matières ?

The table of contents (TOC) is automatically shown once there are four or more headings in the article. There are multiple ways to hide it.

Pour une page
Placez le mot magique __NOTOC__ dans le texte de la page.
Pour toutes les pages
Install Extension:NoTOC
or
Add the following rule to MediaWiki:Common.css: 
.toc, #toc { display: none; }
Par utilisateur
Users can add the same CSS rule to their common.css personal stylesheet.

Comment puis-je changer le texte de l'interface ?

Interface text is altered using the MediaWiki namespace. For each deviation from the default in the site language there is a page MediaWiki:Englishmessagename, and for each deviation from the default in each other language a page MediaWiki:Englishmessagename/languagecode. (Since release 1.9 there are no pages for messages equal to the default.). On creation of a page the edit box autofills with the default. When creating a page to override the default it is useful to first save the default version, to allow diffs with it. See also Help:System message .

How do I edit error messages?

Special:Allmessages contains a complete list of messages (error or otherwise), that can be edited.

You may also add ?uselang=qqx or &uselang=qqx to a URL which will display the name of each messages in the interface.

Comment puis-je changer la langue de l'interface ?

Changez la valeur de $wgLanguageCode dans le fichier LocalSettings.php 

$wgLanguageCode = "fr";

Exécutez le script de maintenance rebuildMessages.php pour reconstruire l'espace de nom MediaWiki.

The new default interface language will be applied to all users who haven't ever customised it.

If you want to provide users the possibility to create and choose pages and interface elements in languages other than the default one of the wiki, you need the Translate extension, which can make your wiki multilingual.

If you want to change the language settings for all existing users, use the userOptions.php maintenance script. For instance, to have all users with English set use French instead, run: 

php userOptions.php language --old en --new fr

How do I remove the article/edit etc tabs?

For a little more control see: User:Subfader/Hide_page_tabs

Edit MediaWiki:Common.css on your wiki, and add this: 

li#ca-edit { display: none; }

See the page source for the various #ca-* ids used in the content tabs.

This will only work for Monobook and derived skins such as Modern and Vector (the default skin), and doesn't actually stop people from editing. To do that, see Manual:User rights .

How do I add/remove tabs throughout my wiki?

See Manual:User group CSS and JavaScript or write your own extension (See: Manual:Hooks/SkinTemplateNavigation ):

For example, to remove the talk tab and then add a tab that always goes to the main page you would save this code in

extensions/AR-Tabs.php:

MediaWiki version:
≥ 1.21
 
<?php
if( !defined( 'MEDIAWIKI' ) ){
	die( "This is not a valid access point.\n" );
}

$wgHooks['SkinTemplateNavigation'][] = 'replaceTabs';
function replaceTabs( &$skin, &$links) {  
	// Remove the talk action
	unset( $links['namespaces']['talk'] );
	$maintitle = Title::newFromText( wfMessage( 'mainpage' )->inContentLanguage()->text() );
	// Add an additional link
	$links['namespaces']['main'] = array(
		'class' => false, // false or 'selected', defines whether the tab should be highlighted
		'text' => wfMessage( 'sitetitle' )->text(), // what the tab says
		'href' => $maintitle->getFullURL(), // where it links to
		'context' => 'main',
	);
	return true;
}

and then add 

require_once("extensions/AR-Tabs.php");

to the bottom of LocalSettings.php

How do I remove a tab on only one page?

MediaWiki version:
≥ 1.9

For example, to remove the Discussion (talk) page tab from the Main Page, on the MediaWiki:Common.css page add: 

body.page-Main_Page li#ca-talk { display: none !important; }

To modify MediaWiki:Common.css you must be an Interface administrator .

See also: Manual:Hide page tabs

How do I remove a tab on all pages

MediaWiki version:
≥ 1.9

For example, to remove the Discussion (talk) page tab on all wikipages, on the MediaWiki:Common.css page add: 

#ca-talk { display:none!important; }

Other tabs to remove are #ca-history, #ca-viewsource, #ca-view (Read tab), #ca-nstab-main (Page tab).

Other drop down menu items you can remove are #ca-watch, #ca-move, #ca-delete.

To modify MediaWiki:Common.css you must be an Interface administrator .

One option is to hide the link using the following CSS in the wiki page MediaWiki:Common.css in your wiki: 

#p-personal #pt-anonuserpage {
    display: none;
}

Another option is, inside your LocalSettings.php file, to use the PersonalUrls hook to remove the link to the talk page of anonymous users: 

$wgHooks['PersonalUrls'][] = 'lfRemoveAnonUserpageLink';
function lfRemoveAnonUserpageLink( &$personal_urls, $title ) {
	unset( $personal_urls['anonuserpage'] );
	return true;
}

To remove the login / create account links from the personal_urls you can use this code in your LocalSettings.php to hook in and remove them: 

$wgHooks['SkinTemplateNavigation::Universal'][] = function ( $skinTemplate, &$links ) {
	unset( $links['user-menu']['login'] );
	unset( $links['user-menu']['login-private'] );
	unset( $links['user-menu']['createaccount'] );
};

How can I suppress actions and special pages?

There are two different ways:

Using .htaccess file

MediaWiki is not designed for this kind of usage! Not all servers support .htaccess file. Note also that this system is not foolproof, it's just one step further than hiding the links (see above).

Suppressing actions and special pages can be useful when you want to create the illusion of a static website via a particular URL or VirtualHost, but also have an 'internal' view that is a true wiki. i.e. if you have an inward facing 'view' of your wiki that users can edit, and an outward facing 'view' that should appear like a static website (no history, no discussion, etc., etc.).

After hiding all the appropriate links (see above), if you are using the Apache web server, you can disable actions and special pages using the following rewrite rules: 

# Lock down the site (disable MediaWiki commands)

RewriteEngine On

#RewriteLog /tmp/rewrite.log

#RewriteLogLevel 9

## See https://www.mediawiki.org/wiki/Special:MyLanguage/Manual:Parameters_to_index.php#Actions

RewriteCond %{QUERY_STRING} (.*action=.*)
RewriteRule .* http://www.my.domain.com?

RewriteCond %{REQUEST_URI} !^/index.php/Special:Search
RewriteCond %{REQUEST_URI}  ^(.*Special:.*)
RewriteRule .* http://www.my.domain.com?

## Catch a trick...
RewriteCond %{QUERY_STRING} ^(.*Special:.*)
RewriteRule .* http://www.my.domain.com?

Above, a request for 'http://www.my.domain.com/wiki/Page_name?action=edit', for example, will be simply rewritten to 'http://www.my.domain.com'. Similarly any page in the Special namespace (except for Special:Search) will be rewritten to 'http://www.my.domain.com'.

Alternatively, you may also serve a "403 Forbidden" for all such requests using: RewriteRule .* - [F]. Remember, this is only a hack, and isn't intended as a solution for a secure CMS.

Note that you will need to adjust the above rules to match your specific URL naming schema.

Other issues to consider when trying to lock down a site like this is the API and POST requests for the wiki content (rather than GET).

Using LocalSettings.php

To disable a specific special page (such as Special:SpecialPages), you may use: 

$wgSpecialPages['Name'] = DisabledSpecialPage::getCallback( 'Name', 'message' );

where Name is the canonical (English) name of the special page to disable, and message is the message to be shown to users when they try to access the special page.

To disable an action (such as edit), you may use: 

$wgActions['edit'] = false;

See API:Restricting API usage to disable an API module.

This is only the basic usages. Usually you may want to disable special pages, actions or API modules conditionally.

How do I change the footer?

See: Manual:Footer , Manual:Configuration settings#Copyright

How can I edit / remove the Powered by MediaWiki image (and possible other images) from the footer?

You can hide the Powered by MediaWiki image by adding the following to your wiki's MediaWiki:Common.css: 

#footer-poweredbyico { display: none; }

If you want to remove it completely, you can use $wgFooterIcons to remove it using this in your LocalSettings.php: 

unset( $wgFooterIcons['poweredby'] );

Note that this will also remove other powered-by icons, e.g. also the one coming from BlueSpice.

If you wish to change the icon images, urls, alt text, or add new icons please see $wgFooterIcons ' documentation.

You can customize signatures in MediaWiki:Signature / MediaWiki:Signature-anon.

For example, changing the entries to [[{{ns:user}}:$1|$2]] ([[{{ns:user_talk}}:$1|talk]]) will put a link to users' talk pages and [[{{ns:user}}:$1|$2]] ([{{fullurl:{{ns:user_talk}}:$1|action=edit&section=new}} Reply]) would give a more direct link.

Users can change their signature in their preferences.

How can I change what the ‎<title> of each page is? Where do I make changes?

Most of the text that you want to change can be found in the namespace of MediaWiki.

In order to change titles, texts, announcements, etc., go to Special:AllMessages, where you will see the text associated with the pages you wish to change. You need to log in as an administrator to edit the protected entries in the MediaWiki namespace.

If you want to change the title in your browser, you need to edit MediaWiki:Pagetitle. Go there and edit it just like you would any other page in your wiki.

In recent versions of MediaWiki, MediaWiki:Pagetitle is $1 - {{SITENAME}} by default. If {{SITENAME}} is producing the wrong text for you, you need to set $wgSitename in your LocalSettings.php.

Don't forget to clear your browser cache after you change your settings.

Does MediaWiki automatically capitalize the first letter of $wgSitename?

Yes. This can be changed using the $wgCapitalLinks configuration setting.

See Manual:$wgExternalLinkTarget

How can I suppress MediaWiki from formatting URLs, tags, etc?

Put "‎<nowiki>‎</nowiki>" tags around the URL or tag.

Example: 

svn co <nowiki>http://svn.example.com/myproject/</nowiki>

Produces:
svn co http://svn.example.com/myproject/

How can I force users to preview before they save?

See: Manual:Force preview , Extension:ForcePreview

How do I add more buttons on the edit page?

See: Manual:Custom edit buttons

How can I get more special characters or tags clickable on the edit page?

For adding more selectable special characters, etc., below the edit field, see Extension:CharInsert .

How can I use a different skin on my wiki?

See Manual:$wgDefaultSkin for more information on configuring your default skin.

Edit the page MediaWiki:Print.css on your wiki and add the following code there: 

#content a.external.text:after,
#content a.external.autonumber:after {
	content: none;
}

This will override the styles defined in the CSS files coming with the MediaWiki source code. For more information, see Manual:CSS .

If instead you want to have the external links underlined in the printable version, then also add the following code: 

#content a.external {
    text-decoration: underline !important;
}

How do I print footnotes at the bottom of each printed page?

Try this StackOverflow solution: Printed HTML per-page footnotes

How do I change the text of the article (page name) tab of my wiki's main page?

To change the text of the tab, as one example used in Wikipedia, you first open the page "MediaWiki:Mainpage-nstab".

After you've done that, click Edit and type in the edit box the text you want to be seen later on the main page - that's it. Don't forget to save the page as well.

How do I change the background color?

To change the background color of the MediaWiki interface outside of the page content and tabs, add the following CSS to the MediaWiki page [[MediaWiki:Common.css]]: 

/* Changes the background color of the bottom and left of each page, up to behind half of the logo: */
body {
  background: red;
}

/* Changes the background color behind the top half of the logo and at top of each page: */
#mw-page-base {
  background: red;
}

This will change the background color outside of the tabs, search, and page content to red. See Manual:CSS for more information.

How do I load external fonts?

This example refers to Google Fonts, a repository of free open-source fonts that you can use with MediaWiki. Go to https://fonts.google.com/, find fonts that you like, and select them by clicking the "plus" (+) icon. Select one or more fonts to be added. Click the tab for the pop-up notification, and then select "@IMPORT". Copy and paste the resulting CSS into [[MediaWiki:Common.css]]. The examples below use Noto Sans and Noto Serif. They are default fonts for Android operating system and have good support for Unicode text. 

@import url( 'https://fonts.googleapis.com/css?family=Noto+Sans|Noto+Serif ');

/* Changes the default font used for MediaWiki to Noto Sans (does not include headings or monospaced text): */
body {
  font-family: "Noto Sans", sans-serif;
}

/* Changes the default font used for MediaWiki headings to Noto Serif: */
#content h1, 
#content h2 {
  font-family: "Noto Serif", serif;
}

How to hide the "Your edit was saved" notification?

Edit the wiki page MediaWiki:Common.css on your wiki to include the line .postedit {display: none;}. See Manual:Interface/Stylesheets for more information.

Comment créer une nouvelle page ?

Il y a plusieurs façons de créer une nouvelle page :

  • Cliquer sur un lien rouge existant ; ou s'il n'y en a pas, en créer un.
  • Aller à l'adresse de la page, par exemple http://www.foowiki.org/index.php/New_page et cliquer sur le lien modifier.

On some wikis, a failed search for a page will contain a link which allows you to edit that page.

How do I delete an old version of a page?

Old versions of page data are retained in the database and can be accessed via the page history features. This is useful for reviewing changes and correcting or reverting undesirable ones, but in some cases, administrators might want to make this information unavailable, for legal reasons, or to reduce the size of the database.

  • Administrators can delete an old revision of a page by deleting the page, and then selectively undeleting revisions to be kept
  • For newer MediaWikis (1.14+), you can enable the core RevisionDelete feature that allows privileged users to remove single revisions from page histories.
See also: Manual:Removing embarrassment

How do I use oversight/delete revisions in the page history?

See: RevisionDelete

You can also delete a page, and then restore only the revisions you want.

Existe-t-il des tutoriaux à propos de l'édition ?

Il y a plusieurs tutoriaux sur l'édition, la plupart sur les projets Wikimédia, tels que Wikipédia. Il y a aussi des références de syntaxe, etc. disponibles sur Meta.

Comment puis-je avoir un format imprimable de la page ?

MediaWiki inclut des feuilles de style qui donnent automatiquement un style approprié à une page pour l'impression ; en utilisant la fonction d'impression ou de prévisualisation d'impression du navigateur, celle-ci doit rendre la page dans un format imprimable.

Vous pourrez aussi voir le format imprimable en utilisant le lien Version imprimable de la boîte à outils.

How do I use templates?

See Help:Templates

Can I use media (images, video, audio, etc.) from Wikimedia Commons in my installed version of MediaWiki?

Yes, this is encouraged through the use of Manual:$wgUseInstantCommons .

How do I use a template as a signature?

When you look at your preferences, you see a check box for "raw signature." But the field will only take a certain number of characters. What if you want more?

You will need to create two pages, possibly in your userspace.

  1. Create the first page (FIRST PAGE)
  2. Go to your preferences, check "raw signature" and put {{FIRST PAGE}} in the signature. Enregistrar las preferéncias
  3. Create a second page (SECOND PAGE) (possibly a sub-page of the first)
  4. Go back to the first page (FIRST PAGE) and do {{SECOND PAGE}}
  5. Go to the second page (SECOND PAGE) and place the code you wish to have for your signature.

If you don't have this structure, you will still be inserting all your signature code into the raw code wherever your signature is used, because the software will insert "SUBST" in your preferences. You may not mind this, in which case you only need one page. If you want the raw code to only display {{FIRST PAGE}}, which looks a lot cleaner, then you need to use the two-page structure.

How do I add the sandbox functionality to my installation of the wiki?

In wiki terms, a sandbox is simply a "play pen"; a page which users can mess about in. This is an ordinary page created in the normal manner, and can be located wherever you like. There is no special sandbox functionality built into MediaWiki.

Users often inquire about the Wikipedia sandboxes, which seem to be self-emptying. This is not quite correct; there are a number of volunteers who run bots to clean these up and return them to a certain state at regular time intervals.

See also Extension:SandboxLink which will add a link to user's personal sandbox (i.e. a subpage of personal user page) to personal tools menu.

You need to install the SandboxLink extension.

Instructions

Templates imported from other wikis (such as Wikipedia) don't work for me

You probably need to install some extensions used on the source wiki, such as Scribunto , TemplateStyles , ParserFunctions or sometimes Cite . Also, make sure that you copied all site CSS and JavaScript required by the template.

Personalisation avancée

I want to have multiple wikis, but only require registration once

  • If you're starting from scratch or you're switching from one wiki to multiple, you can use $wgSharedDB and $wgSharedTables to have all wikis share the user table of the "main" wiki.

You can share other tables as well, as long as they don't contain any data dependent on non-shared tables or data specific to one wiki. See Manual:Shared database for examples and more information.

  • If your wikis are already established and you want to switch to a single sign-on, you can use the CentralAuth extension.

It has a few more features than a shared user table, but it's more difficult to configure and it's tailored toward a Wikimedia-style setup. However, it is easier than attempting to completely merge multiple user tables into one.

How can I allow use of HTML tags?

See Manual:$wgRawHtml as well as Manual:$wgGroupPermissions e Manual:Preventing access .

  Caution: This can be easily abused to attack users

See Extension:Secure HTML and Extension:HTMLets for ways to make this safer.

How do I fix problems or add features to MediaWiki?

The basic steps to improving MediaWiki (that is, becoming a MediaWiki developer) are:

  • Download the Git "clone" of the MediaWiki source code
  • Get a server, a database, and PHP running on your computer (this can be annoying, so please ask for help if something isn't working)
  • Get MediaWiki running on your computer off that Git checkout (can be annoying as well, so, ditto)
  • Fix the problem or add the feature you were thinking of
  • Edit the source code of the relevant file(s) to fix the problem

...l'espace de nom Help de ce site est-il vide ?

cependant l'espace de nom Help est encore en construction. It's up to you how much or how little help you give to your site visitors and whether this relates to other aspects of your site. Obviously you can easily link your visitors to help resources elsewhere.

Nous n'avons pas actuellement un ensemble propre et internationalisé de pages d'aide sous licence libre. However, if you want to copy in some help information onto your site, about how to use a wiki (a MediaWiki powered wiki) you are free to copy the Help:Conte

...certaines de mes images n'apparaissent pas après une mise à jour ?

Plusieurs utilisateurs ont rapporté que, après une mise à jour ou un déplacement de leur wiki, plusieurs images ne s'affichaient pas. Les fichiers existent, et la page de description de l'image montre un type MIME unknowncode>/unknown (inconnu) et dans certains cas un avertissement concernant les fichiers potentiellement dangereux.

La solution à cela est d'exécuter le script de maintenance maintenance/rebuildImages.php à partir de la ligne de commande. Cela configure les types MIME pour tous les fichiers de la base de données, et devrait rétablir les choses à la normale.

MediaWiki 1.21 and newer implements responsive images. Due to a bug, if the server locale is set to one that uses commas instead of dots for representing a decimal point, images may not render on some browsers/devices. This can be confirmed by inspecting a thumbnail of a medium or big image on a page with the browser tools, looking at the HTML code, and see if the srcset attribute contains commas instead of dots when representing the 1.5x value.

...tous les fichiers PNG ne sont pas affichés en vignette ?

Après le téléchargement d'une version plus récente de PHP, il est possible qu'une fonction MimeMagic.php soit utilisée pour détecter les types MIME, particulièrement la fonction PHP générique mime_content_type, qui échoue à détecter les fichiers PNG. Cherchez sur les web mime_content_type png pour avoir des informations sur la résolution de ce bug pour la version de PHP, peut-être en éditant votre fichier magic.mime.

…can't I download MediaWiki 1.43?

MediaWiki 1.43 is in a development state at present, and has not been packaged into a general release. The code can be downloaded from Git if desired. Or, if you want the latest development version packaged as an archive, get it at mediawiki-master.tar.gz (GitHub).

...ça ne marche pas ? Ça marche sur Wikipédia !

Wikipedia and other Wikimedia web sites use the current version of the code in development; at present, this is MediaWiki 1.44.0-wmf.4 (a8dd895), pulled from the current development branch. Coupled with the use of several extensions, this means that functionality between these wikis and your particular setup may differ.

  • To check what version a Wikimedia wiki is running, as well as what extensions are installed, visit the Special:Version page for that wiki

…do I get a 403 Forbidden error after setting permissions on my Fedora system?

Fedora enables SELinux by default. Instructions for setting SELinux permissions for MediaWiki are available.

…do I get Installing some external dependencies (e.g. via composer) is required?

Many hosting providers only handle zip archives, and we only provide gz compressed tar archives, thus the archives has to be recompressed before uploading. This should not be a hurdle, but it seems like some archive tools occasionally fail to include all files in large archives. When this happen the vendor folder is left out, leaving the user with the rather non-explanatory error message.

Use a command line tool when recompressing the tar archive into a zip archive.

…do I get logged out constantly?

This is probably related to cookies or session data. See Log in problems for information.

If this is happening constantly to all users, it probably means that caching is misconfigured. Setting $wgSessionCacheType = CACHE_DB; can be used to determine if caching is the cause of the problem. If that solves the problem, you should still investigate what is wrong with your caching configuration.

…is it a good idea to keep user accounts?

At many times you just want to remove a user account out of the wiki either because it belonged to a spammer account or you just feel like it. The appropriate choice is to block the account or rename it if needed. Here is why:

Do I just remove this row from the user table?

Rob Church posted the following regarding this issue on the wikitech-l mailing list:

If the user has made edits, then removing rows from the user table cause theoretical loss of referential integrity.

Now, to be honest with you, I can't think of any conditions where this would cause an actual problem; "undefined behaviour" is the phrase we use.

What I'd suggest doing, to be on the safe side, is running a couple of quick updates against the database: 

UPDATE revision SET rev_user = 0 WHERE rev_user = <current_user_id>

UPDATE archive SET ar_user = 0 WHERE ar_user = <current_user_id>

What this will do is cause MediaWiki to treat the revisions as having been made anonymously when generating things like page histories, which should eliminate any problems caused by these routines attempting to check user details from other tables.

If the user has caused log entries, i.e. rows in the logging table, or uploaded images, then the situation becomes trickier, as you'll have to start mopping up all the rows everywhere and it could become a bit of a mess, so if the user's done anything other than edit, I would strongly recommend just blocking them indefinitely.

If the username is offensive or undesirable, then you could consider renaming it using the RenameUser extension.

Another option is to give Admins the 'hideuser' right, and indefinitely block the user with the Hide username from edits and lists option selected.

Extension:UserMerge is also useful.

…is the number of pages so low on Special:Statistics?

By default, $wgArticleCountMethod is set to link. This means the number of "Content pages" on the Special:Statistics page only counts pages which include at least one internal link. This can be changed by setting $wgArticleCountMethod to any. Afterwards, run updateArticleCount.php and/or initSiteStats.php . (On Wikimedia websites, initSiteStats.php is run on the 1st and 15th of each month.) There might still be wrong behavior, see for example phab:T212706.

Anti-spam

Comment puis-je utiliser $wgSpamRegex pour bloquer plus d'une chaîne de caractères ?

$wgSpamRegex est un puissant filtre pour le contenu d'une page. Ajouter plusieurs items de regex est parfois maladroit. Considérez le code suivant : 

$wgSpamRegexLines[] = 'display\s*:\s*none';
$wgSpamRegexLines[] = 'overflow\s*:\s*auto';
[...]
$wgSpamRegex = '/(' . implode( '|', $wgSpamRegexLines ) . ')/i';

Cet exemple de code permet d'additionner facilement des items à la regex sans trop compliquer à chaque occurence. Il montre aussi deux filtres populaires qui bloquent quelques unes des attaques de spam les plus courantes.

I'm getting a strange error. What now?

I tried that but it didn't work

I had a problem, I came to this page and it told me how to fix it. But it didn't work, the problem is still there!!!!

Nine times out of ten this is because you didn't clear your cache. The simple test for this is to request a page that hasn't been requested before. Select the part of the URL in the address bar that contains the page title (e.g. Main_Page). Twiddle your fingers on the keyboard for a while, hit enter. Check if the problem is on that page too.

MediaWiki uses both a server-side cache and a client-side cache, so clearing your browser cache is often not enough. See the relevant entry above for more details.

Here are some other things to check:

  • Were you editing the right file? Try inserting some garbage into the file you edited, does it break anything?
    • A great debugging tool in this case is to create a file called phpinfo.php, containing only <?php phpinfo() ?>.

Upload it into your web directory and invoke it with your browser. Check the document root and the path to php.ini.

  • Were you editing the right part of the file?

Did you create a duplicate entry in php.ini? Add new settings to the end of LocalSettings.php, not to the beginning.

  • If you created a .htaccess, are you sure AllowOverrides is on?

Ask your hosting provider.
