Creating custom skins

Hello. I have a custom CSS (also JS but not entirely mine) for the Vector 2022 skin as I find it terrible at its default, but CSS restricts me to narrow customizations as I can't change the HTML structure, and I think changing the HTML structure with JS that much without causing big problems would be very hard as it will be done over an existing structure (even the CSS side causes many hard-to-solve problems for the same reason). Also, the updates the skin gets can break my customizations, very annoyingly. So, I want to create my own MW skins and use them in WMF wikis. How can I do that without too much difficulty?

@TheDJ The links I saw don't help, how can I install or enable intl? RuzDD (talk) 19:56, 11 February 2025 (UTC)

@RuzDD Basic (web) development knowledge is required for those who want to develop skins, there is no 'easy' way to learn how to develop skins. Maybe ask AI to help you if you still need to learn. I'm not sure what prompted you to ask about intl, but most likely it refers to php intl, which are additional features for php itself, that you have to enable or install for you PHP install. —TheDJ (Not WMF) (talk • contribs) 09:09, 12 February 2025 (UTC)

@TheDJ I got an error message saying I need to install or enable intl, but these pages don't tell how can I install or enable it in XAMPP's Apache. I already have basic web developement knowledge.

I uncommented ";extension=intl" (there was no ";extension=php_intl.dll") in php.ini and looks like it worked, thanks. I will write here if I have another problem. RuzDD (talk) 14:00, 12 February 2025 (UTC)

I got this error:

Cannot access the database: :real_connect(): (HY000/1045): Access denied for user 'root'@'localhost' (using password: YES).

Check the host, username and password and try again. If using "localhost" as the database host, try using "127.0.0.1" instead (or vice versa).

I tried both but they don't work. (I ran XAMPP as admin and both Apache and MySQL are running.) What can I do @TheDJ? RuzDD (talk) 14:12, 12 February 2025 (UTC)

I solved this problem and completed the installation and I will write here again if I have a problem creating the skin. RuzDD (talk) 13:06, 13 February 2025 (UTC)

@TheDJ The page you linked first tells three ways, but I don't know anything about the mustache templates or whatever gives the data. To clarify, with my current knowledge, I can make an HTML structure giving the look of the skin but can't make the skin show any data. Can you please help me about that?

Location Map Error

I'm having an issue while attempting to implement a location map on my wiki. (Currently running MediaWiki version 1.43.0 after being updated as the result of a previous help request.) Instead of properly displaying a box and floating the map right, it does neither of those things and instead displays the text "class=notpageimage|" below the image. (Screenshot) This error does not occur in the implementation on Wikipedia sandbox. Also, whether or not the PageImages extension is enabled in LocalSettings.php doesn't seem to make a difference. –Noha307 (talk) 05:10, 24 February 2025 (UTC)

Try to export all templates related to the Location map and import to your wiki. It can help. Fokebox (talk) 09:33, 24 February 2025 (UTC)

I tried updating both the Location map+ and Location map~ templates with the import/export function, but it unfortunately didn't help. I also tried inserting a regular image thumbnail from Wikimedia Commons, since I hadn't tested that yet and it worked fine. I also tried reducing the number of entries and amount of syntax in the template to the bare minimum, but that didn't help either. I did find one discussion that suggested running something called "initImageData.php" might help, but I am not familiar with what that is. –Noha307 (talk) 05:00, 3 March 2025 (UTC)

I got exaclty same problem, also running MediaWiki version 1.43.0. I noticed that when i changed skin from Vector to Cologne Blue everything works correctly. Can't find really source of this problem. Screenshot SANtosito (talk) 12:11, 13 March 2025 (UTC)

Pagelinks.sql.gz file

I am trying to work with the Pagelinks file in order to extract the number of articles that link to a specific Wiki page (same idea as can be seen in the "What-links-here" tool.

However, when I loop over this sql like file, I find very weird cases of links that doesn't seem to exist in Wikipedia.

For example, the first line in the file indicate that there is a link between page ids 1939 and 2. PageID 2 doesn't even seems to exist.

Even when I look on pageIDs that do exist, the link indicated in the file does not exist in the actual wiki page.

Am I missing anything? Avrahami-isr (talk) 02:07, 1 March 2025 (UTC)

Restricting edit access to a accounts with a specified verified email domain

I am attempting to restrict editing to users with a verified email of a specific domain (e.g. only users with an @ example.net email). I found this post from several years ago, but the hook it's using doesn't seem to work with newer versions. The code I'm using now looks something like (at the bottom of LocalSettings):

$wgEmailDomain = '@icloud.com'; // Set the email domain to check

  $wgHooks['ConfirmEmailComplete'][] = function ( $user ) use ( $wgEmailDomain) {

         if ( preg_match('/' . preg_quote($wgEmailDomain, '/') . '$/i', $user->getEmail()) ) {

         $user->addGroup('domain_member');

     }

     return true;

};

No matter what event I tie this to (e.g. ConfirmEmailComplete, AbortNewAccount, etc.) I always wind up encountering errors when I attempt to run it. Any suggestions on fixes or a different way to implement? Thanks! Ironblade101 (talk) 03:12, 4 March 2025 (UTC)

Scala Santa e Oratorio di San Silvestro in Palatio

Stavo modificando il post sulla Scala Santa (https://it.wikipedia.org/wiki/Scala_Santa), inserendo la correzione:

* la cappella di San Lorenzo cui si accede dalla prima rampa di scale a destra;

Prima questa cappella era citata erroneamente come oratorio di San Silvesto in Palatio, con una foto però corretta di S. Lorenzo.

Fatta questa modifica la foto della cappella di S. Lorenzo è sparita e non sono in grado di recuperarla, e cliccandoci mi porta a una pagina di disambiguazione che non cita S. Lorenzo.

Anche la pagina https://it.wikipedia.org/wiki/Oratorio_di_San_Silvestro_in_Palatio contiene molte citazioni errate: questa è la cappella di San Lorenzo alla Scala Santa.

Ho bisogno di aiuto più competente della mia incompetenza, anche perchè in futuro ho intenzione di inserire molte piante di monumenti/siti in formato .bmp e non saprei proprio come fare.

For your own wiki, see Manual:Configuring file uploads and then Help:Images for the syntax. For Wikipedia, you use the upload link on Commons (c:Special:UploadWizard) and then use the same syntax to add the image to the relevant article(s) in any Wikipedia. Tactica (talk) 02:15, 6 March 2025 (UTC)

"Edit" only appears on Main Page but not on "Discussion"

Recent changes missing after migration

Hello all,

I am running multiple MediaWiki 1.43 instances. As a part of my work, I routinely copy Wikis from my PROD to my DEV environment. I do this by copying /images folder, LocalSettings.php and restoring a mysqldump of PROD databases to a DEV MediaWiki instance. This has worked flawlessly for months.

Recently however, "Recent changes" is empty after the restore in DEV, but only for some Wikis. I've tried rebuildrecentchanges.php which did nothing, and rebuildall.php which did "Removing 'recentchanges.rc_timestamp' default value. Modifying rc_timestamp field of table recentchanges...done." Still no recent changes, though. I've tried dumping with --routines and --skip-triggers and a whole lot of other MySQL parameters, but no joy. I've compared the recentchanges table in DEV and PROD, and from what I can see they are identical. I am by no means a MySQL expert, though.

Anyone who has an idea about what is going on? I'm worried about other things going missing during a copy without me noticing.

Editnotice in discussiontools-ui-replyWidget

Hi there, I have an editnotice on my talk page with my pronouns. This editnotice shows up when the source is being edited or when someone starts a new topic.

Request for Instructions on Hiding Public Logs for Anonymous Users (MediaWiki 1.39.3)

Hello,

I am using MediaWiki version 1.39.3 and I would like to know how to hide all public logs that are accessible via Special:Log for anonymous users. Could you please provide me with step-by-step instructions on how to accomplish this?

Thank you in advance.

Best regards Sdelriog (talk) 13:04, 7 March 2025 (UTC)

You can try removing all read access from anonymous users as described in Manual:Preventing_access. It should be noted however that wikis are about transparency, so you might be better off with a CMS if you want to lock down things like this. —TheDJ (Not WMF) (talk • contribs) 10:58, 10 March 2025 (UTC)

Mylittlewiki.org

This part of wiki is an important place for collectors and neerds.

Problem is, the original author does not seem to exist any longer. She disappeared years ago.

There is only a few people over the world that can update now. And they're drowning in information that should be added.

Is it only the original author that can expand the group of administrators? Or is it possible to make some more people admin?

Please help. We're getting desperate.

Christine Tomtlund. Paintdelicious (talk) 15:54, 7 March 2025 (UTC)

You need a "bureaucrat" account to create admin accounts, and it looks like the owner is the only one with this right on that site. If you absolutely must have more admins and the owner can't be reached, maybe you should consider using Special:Export to export the articles and a spider to download the 8.48 GB worth of images and then replicate the wiki under a new domain.

Upgrading Mediawiki through export and import

Dear all,

I want to upgrade my Mediawiki installation from 1.42.1 to the latest LTS 1.43.0.

I've read the upgrade documentation and it seems to me quite difficult and error prone.

Considering that:

• my wiki is really small (20 pages more or less);
• I only modified 4-5 lines in LocalSettings.php;
• I only installed a couple of extension and I'm using the default skin;

I'm thinking of:

• creating a new subdomain;
• making a fresh installation of 1.43.0 on the new domain; with all extensions I'm using on 1.42.1;
• merging the old LocalSettings.php (1.42.1) into the new LocalSettings.php (1.43.0);
• copying the images directory;
• export all pages an importing them in the new wiki (Special:Export + Special:import)

Do you think this could be easier than following the upgrade procedure?

Regards,

Massimiliano 94.32.36.29 00:25, 8 March 2025 (UTC)

For a wiki with 20 articles and a couple of extensions, your plan sounds overkill. It would be far simpler to just overwrite your MW installation with 1.43.0 and updated versions of those extensions, backup the database just in case and then run maintenance/update.php to upgrade it. This presumes you have all the requirements to run MW 1.43. Tactica (talk) 02:37, 8 March 2025 (UTC)

It's not meant to be a great idea to overwrite the files. But it would be nearly as easy to use a separate directory to download the 1.43 files and compatible versions of the two extensions, copy the images and LocalSettings.php across, and run update.php. Jonathan3 (talk) 23:28, 8 March 2025 (UTC)

Thanks for your reply. What do you mean by "run maintenance/update.php"?

If I run now mysiteaddress/maintenance/update.php I get

Forbidden

You don't have permission to access this resource.

Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.

Is the "maintenance/update.php" something that's contained in the update package?

Regards,

Massimiliano 193.207.202.129 01:12, 16 March 2025 (UTC)

See Manual:Update.php. You probably need sudo for it to work, even if the documentation here doesn't say so explicitly:

$ cd maintenance
$ sudo php run.php update.php

Jonathan3 is right BTW, it's safer to install 1.43 in a separate directory and work with that. Tactica (talk) 13:15, 17 March 2025 (UTC)

Double links after validate a text modification

Hello

I installed Mediawiki on a server (Debian/Apache), directory /var/lib/mediawiki

In the directory /var/www/html I added a link

docs -> /var/lib/mediawiki

When I call the link mon-site/docs/index.php/Accueil I display the page, it works

But when I want to make a modification of a page and I click on Validate. I don't return to the previous page. The URL has been change, the link to my site is double mon-site/docs/mon-site/docs/index.php/Accueil

What parameter does this modification make ?

Unable to import wiki dump using Special:Import or importDump.php

Hi, I'm trying to fork my Fandom wiki, eventually to a custom domain, but for now only locally hosted. I'm having many issues importing the xml dump of my wiki to my new database. I'm in way over my head, I have no experience with mysql or php, just the frontend stuff.

Initially I tried using the maintenance scripts such as importDump.php as per the Manual:ImportDump.php article, but I keep getting this error in return:

PS D:\Wiki Files\htdocs\wiki\maintenance> php importDump.php --conf ../LocalSettings.php /destinycollect_pages_current.xml --username-prefix="w:c:destinycollect"

*******************************************************************************

NOTE: Do not run maintenance scripts directly, use maintenance/run.php instead! Running scripts directly has been deprecated in MediaWiki 1.40. It may not work for some (or any) scripts in the future.

*******************************************************************************

PHP Warning: fopen(/destinycollect_pages_current.xml): Failed to open stream: No such file or directory in D:\Wiki Files\htdocs\wiki\maintenance\importDump.php on line 296 Warning: fopen(/destinycollect_pages_current.xml): Failed to open stream: No such file or directory in D:\Wiki Files\htdocs\wiki\maintenance\importDump.php on line 296 fopen(/destinycollect_pages_current.xml): Failed to open stream: No such file or directory

I'm not sure if I'm doing something wrong, or if the script just no longer works as the warning suggests. I see it's apparently having trouble finding my xml file, though I placed it in the maintenance folder for simplicity's sake, but like I said, I don't know if that's the actual problem or not. I also couldn't find anything explaining how to work run.php for this purpose.

Next I tried the Special:Import page of my wiki. I have had multiple different errors with this method, the following being the latest one:

[1b039779a0e57e43db782d99] /wiki/index.php?title=Special:Import&action=submit Wikimedia\Rdbms\DBTransactionStateError: Cannot execute query from LCStoreDB::get while transaction status is ERROR

Initially, I was running into issues with the maximum execution time, which was defaulted to 120 seconds in my php.ini file. I changed it to 3600 (really not sure how long it should take, my wiki is ~320 articles with various categories and templates), and after a couple errant issues like the attached one, I eventually ran into a problem with the memory limit being exceeded. I changed that from 512M to 1024M. Then I set it to run overnight, and this morning it had reached the time limit again, which I increased again to 24 hours. Now I'm running into the attached error each time.

The approach used in the Manual:Importing XML dumps article is appealing, but I honestly have little clue what I'm looking at here. It's clearly intended for those with more experience.

I tried to provide my LocalSettings.php and php.ini files for reference, as well as screencaps of my error messages, but external links are unallowed it seems. In any case, help would be greatly appreciated. As I said, I don't know what I'm doing! If anyone has any up to date learning resources as well, I'd be glad to be pointed in the right direction. Thanks! Ironybee523 (talk) 17:58, 8 March 2025 (UTC)

@Ironybee523: It looks like one issue is that you're missing a leading dot in the filename: /destinycollect_pages_current.xml doesn't exist, but ./destinycollect_pages_current.xml presumably does? Sam Wilson 08:58, 9 March 2025 (UTC)

Thank you for the reply. I'm not sure what the deal was, but the Special:Import page eventually worked when I wasn't looking. Well, it didn't say it worked, but when I checked the site, everything had loaded up. Ironybee523 (talk) 15:41, 14 March 2025 (UTC)

Automatically Place File Uploads into a Category

When I upload a file, it's File:Filename.ext page is automatically created, but it's empty. I'd like to automatically place it into a category.

I would love if it were default to this namespace, where I don't even need to run a script to edit the empty page.

I see Manual:Creating pages with preloaded text and some extensions that look like they'd work on normal pages, but not the File namespace.

Is this possible? 70.160.223.43 04:27, 11 March 2025 (UTC)

If all you want is have all the uploaded files placed in one or more categories, the most simple way I can think of based on the default upload mechanism is a template like Template:Information inserted in MediaWiki:Upload-default-description, modified to suit your specific requirements.

Could not create directory when uploading images.

• MediaWiki: 1.43.0
• Php: 8.2.12
• XAMPP: 3.3.0
• Windows 10 22H2

The wiki runs on a Windows 10 server using XAMPP. XAMPP is installed at C:\xampp. The wiki is inside the directory C:\xampp\htdocs\wiki.

When uploading some pictures, sometimes the upload fails for specific pictures with the translated error:

"Could not create directory: « mwstore://local-backend/local-public/8/80 »

The actual error is (the wiki is running on FR language):

"Impossible de créer le répertoire « mwstore://local-backend/local-public/8/80 »."

The link in the error changes depending on the picture. The error will keep occurring if I try to upload the same file.

The wiki is internal; so it's not accessible to the Internet. There's not much information out there about Windows installs or XAMPP in particular. Most solutions pertain to Linux installs and it involves setting permissions on the directories. I'm not sure which user I need to give permissions to, but I already tried "Guest", "Everyone" and so on just to test and nothing seems to resolve the issue.

It appears the issue affects files that try to write in an existing directory structure. If the image is being created in a new directory, then the error doesn't occur.

Note: The directory in the error actually exists in the images folder in the wiki directory.

Edit: This error shows in the log: [FileOperation] Wikimedia\FileBackend\FSFileBackend::doPrepareInternal: directory C:\xampp\htdocs\wiki/images/8/80 is read-only

I checked the directory and the read-only flag is showing a square instead of a checkmark. If I remove it and to everything under that directory, it automatically reverts back to a square again.

Edit2: Ultimately, I had to modify the FSFileBackend.php file. I commented out the line 516 to 518, which were the following:

		//} elseif ( !$isWritable ) {
		//	$this->logger->error( __METHOD__ . ": directory $fsDirectory is read-only") ;
		//	$status->fatal( 'directoryreadonlyerror', $params['dir']) ;

This is not an ideal fix, but it works for now. I figured out that there is probably a bug with the is_Writable php function that returns false even if the directory is writable.

If anyone knows a more proper solution, please respond and I will implement it.

Requesting Steward-related Assistance

explainxkcd.com, running MediaWiki software, has no active bureaucrats. As a result, no old admins can be de-sysopped and no new admins can be promoted. Can MediaWiki stewards promote someone on the wiki to ‘crat status? 205.174.240.242 19:55, 12 March 2025 (UTC)

No, because MediaWiki.org (that is a website) stewards cannot take over random third-party websites on the interwebs which occasionally installed the same piece of software on their machines. Malyacko (talk) 06:22, 13 March 2025 (UTC)

identifying Author's Comments

Hello everyone,

I'm new here and just set up the Comments Extension. I'm working on T155466 and looking to highlight author's comments on blogs while excluding comments on articles (if enabled).

I previously asked about this on mw:Extension talk:Comments, but there doesn't seem to be any activity there.

Could someone advise on:

• Identifying the author's comments programmatically.
• Differentiating between blog and article comments.

Any guidance would be appreciated. Thanks! Parv ch (talk) 12:12, 13 March 2025 (UTC)

Is there way way to mass delete a list of bot users?

Hey Everyone. My wiki has been slowly invaded by bots since last March. There are a little over 1000 bots. They haven't made any edits or created pages to my knowledge, but I do have a bunch of dead accounts that I'd like to get rid of. There were only supposed to be about 10 uses in my wiki at the point I noticed the bots. I tried the built-in mediawiki remove unused accounts script, RemoveUnusedAccounts.php, but it only returns three accounts, which is a lot less than the 1000 I need removed. User merge is another option to delete accounts, but doing that for each bot would be super time-consuming.

Is there any way to just input a list of accounts you want gone and have them blocked and/or removed?

I'm on Mediawiki 1.41. Thanks for any input in advance. 71.185.78.14 17:58, 13 March 2025 (UTC)

One of the first things that came to my mind was the blockUsers.php maintenance script , which (IIUC) would allow you to provide a list of accounts to mass-block. However, that script doesn't currently support blocking accounts with the hideuser option enabled (which, while not deleting the accounts from the database, would result in MediaWiki pretending that they don't exist). (I've filed T388841 to request that this functionality is added to blockUsers.php.)

Someone else might have an idea about how to mass-delete/mass-hide the accounts in the current situation - apologies that I can't be more help myself! All the best, ‍—‍a smart kitten_[meow] 07:25, 15 March 2025 (UTC)

option not to display the group name in <ref> tag ?

is it possible to reduce the scope of the <references/> tag to a section only, without using the printed group name before the index which overloads the contents where the <ref> tag are used ? That means that the [1][2][3]...would concern the section (paragraph). The 'group=' principle is still used but group name is not displayed in this case. This is useful when references are used in an array of contents and the URLs are displayed just below. Thanks. -- Christian 🇫🇷 FR 🚨 (talk) 07:44, 15 March 2025 (UTC)

That's an enhancement request for Extension:Cite, not something related to MediaWiki itself. Tactica (talk) 13:12, 15 March 2025 (UTC)

I didn't follow your question completely so might have missed the point... but I have a feeling that if you transclude a page, and that page has a "references" tag, it only shows references relating to the transcluded page. You could do that for each of your sections. Jonathan3 (talk) 22:30, 15 March 2025 (UTC)

My understanding is that he simply wants e.g. <ref group="Blah" name="myref"/> to display ^[1] rather than ^{[Blah 1]} in an article, hence my comment. Tactica (talk) 23:24, 15 March 2025 (UTC)

Thanks. My suggestion above would still work for that, in an unwieldly way! But it looks like it's not an enhancement request: it's all described at Help:Cite#Grouped_references. If you create the page "MediaWiki:Cite_link_label_group-Blah" with "1 2 3 4" etc then the word "Blah" won't be displayed. Jonathan3 (talk) 23:38, 15 March 2025 (UTC)

Yup, you're right. I never used customization so I didn't even think it could be done this way, oops! Tactica (talk) 12:51, 17 March 2025 (UTC)

There is NO question of transclusion here. The array is already in the page, in any paragraph under a title == and I would like it light and with the references just after for immediate reading. so @Tactica yes you are right it is what would be nice. Thanks. may be i m more clear now. --Christian 🇫🇷 FR 🚨 (talk) 08:53, 18 March 2025 (UTC)

blending transclusion with numbering

I am using version 1.36.1, and I am trying to figure out if there is a way to transclude text without breaking numbering.

Thanks for any guidance.True Pagan Warrior (talk) 14:57, 17 March 2025 (UTC)

Setting a default tabber

Dear ∀,

In our wiki we employ extension:tabberNeue to present different versions of elements of an XML schema.

Some elements have been deprecated in the newest version, so we would prefer to set the last existing version as the default view. E.g. on https://wiki3.railml.org/wiki/IS:infrastructureState we would like to set #3.2-0 as the default view.

Is there a way to achieve this?

Thank you in advance.

too many files

I am running a wiki for 9 years now, but recently have the problem that my hoster tells me that I have reached a limitation of file numbers (it says 260,000, but actually it is 262,144). The wiki has about 48,000 uploaded files (mainly images), but of course there are all the thumbnails, some archived and some deleted files.

What is the safest and easiest way to get rid of (somewhat) unnecessary files? And how much would that help in the medium to long term? Kommunalflaggen.eu (talk) 23:44, 18 March 2025 (UTC)

and I should perhaps add, that it took me some time to find out that this limitation created my login, edit and file upload problems.

Not consistently, but intermittedly I had got the following error messages:

Manual:Common_errors_and_symptoms#Login_page_warns_about_cookies_disabled

Manual:Common_errors_and_symptoms#Error:_Could_not_open_lock_file_for_"mwstore://local-backend/local-public/./../image.png

These error messages were not helpful! Kommunalflaggen.eu (talk) 23:52, 18 March 2025 (UTC)

I'm fairly certain you can just delete all the thumbnails. Unless you change settings, they'll eventually regenerate themselves. It might reduce your file number by quite a lot, as (for example) maybe you've got a thumbnail for every page of thousands of PDF documents. Jonathan3 (talk) 00:36, 20 March 2025 (UTC)

How to add custom font in Commons.css?

Hello!

I recently installed MediaWiki and it works just perfect. 👍👌

I'm in the process of customizing the wiki and would like to add any custom font to Common.css. Although I tried, it didn't seem to work. I've sought help from ChatGPT, but I'm still not sure what I'm doing wrong.

Here's the code I put in Common.css:

@font-face {

    font-family: 'MyCustomFont';

    src: url('/path/to/mycustomfont.woff2') format('woff2'),

         url('/path/to/mycustomfont.woff') format('woff');

    font-weight: normal;

    font-style: normal;

}

body {

    font-family: 'MyCustomFont', sans-serif;

}

Please leave any comments on how I can improve this. JayAndrewBoy (talk) 10:05, 19 March 2025 (UTC)

Something like @import url( 'https://fonts.googleapis.com/css?family=...' ); should work. Then you can use the ... part in "font-family".

Also, I'm not sure but think you might need to list other elements as well as "body" to get everything to work, e.g. h1, h2, h3, button etc. Jonathan3 (talk) 00:33, 20 March 2025 (UTC)

foreach error from MimeAnalyzer

The error log on my wiki's server has lately been filled with constant repetitions of this PHP error, always citing MimeAnalyzer:

I see the line it references in MimeAnalyzer.php is in this block:

foreach ( $this->mimeToExts as $mime => $exts ) {
    foreach ( $exts as $ext ) {
        $this->extToMimes[$ext][] = $mime;

I'm not sure how to diagnose this, so I was curious if anyone might know the cause. Any insights are much appreciated!
