Topic on Project:Support desk/Flow

I successfully did the database update using the update php script. I had to change permissions on everything, but I am getting "This site can't be reached" on Chrome, and a slightly different message on firefox. I know the site can be reached, because if I put phpinfo(); in various places in my LocalSettings.php, it displays the phpinfo instead of giving me the bogus message. My LocalSettings has been being modified for many years, and so I tried making a new one, but that didn't seem to solve things either (though I quite likely might have made a mistake with that). The error remains the same. There are no errors or warnings I can find in /var/log/apache2/error.log. I get nothing with

error_reporting(E_ALL);

ini_set("display_errors", 1);

at the top of my LocalSettings.php

Does anyone have any idea what might be my issue, or even how to debug this?

Thanks,

Rob

Try placing this code at the end of LocalSettings.php

error_reporting( -1 );

ini_set( 'display_errors', 1 );

if that not works, try to reinstall the mediawiki, by accessing the mw-config directory, example:

wiki-site.com/mw-config

You need the $wgUpgradeKey value located within the LocalSettings.php.

One more option is to do a clean installation of mediawiki, using the same old database.

You also need to update all active extensions to the matching version of mediawiki.

Can I just disable the extensions in LocalSettings.php? I was using the Math, Import Users, and EmbedVideo. I tried commenting out anything having to do with extensions or anything else that might be doing extra things. I'm trying the "divide and conquer" approach. Before I started on this approach a phpinfo(); early on in LocalSettings.php would print out, but later in the file it would not. Commenting out offending lines, it now prints if a phpinfo(); is put on the last line. However, removing it gives the dreaded "can't be reached". Here is a copy of my commented LocalSettings.php, with the sensitive data removed.

I am also not understanding what you mean by "

try to reinstall the mediawiki, by accessing the mw-config directory, example:

wiki-site.com/mw-config

You need the $wgUpgradeKey value located within the LocalSettings.php." Could you provide a link to instructions or something with more details?

I just noticed the following warnings at the bottom of the phpinfo page when I have it at the end of LocalSettings.php.

These warnings also appear in /var/log/apache2/error.log, but don't appear on the screen or in the log if I take the phpinfo(); out of the last line in LocalSettings.php.

Try to reinstall you wiki again, by visiting this URL, yourwiki.com/mw-config.

mw-config is the web-based mediawiki config/installation.

once visited, you will be prompted to either install (read the note) or reinstall the wiki which includes some initial configuration like wiki name, database configuration, and some other basic wiki configuration like enabling extensions, skins, etc..

Note: to reinstall, you have to rename the file LocalSetting.php, to some other name like LocalSettings.back. then you will get another fresh copy of the LocalSettings.php after finishing the installation, use it as a new LocalSettings.php.

I can't get that far. I get "This site cannot be reached."

If I put phpinfo() in as the last line of LocalSettings.php, I get the phpinfo with the above warnings, but without it, all I get is "This site cannot be reached."

Okay, so I went to the latest (1.39.1) and used the mw-config on that. If I used my LocalSettings.php, I get the same errors. If I use a bare bones LocalSetting.php, it loads the page, but extensions I use are not working. The minute I put any $wfLoadExtension( "Math" ), or any other extension I need, I get "The page isn't working" message. As far as I can tell the permissions are the same.

Huzzah! I got the extensions to work. I had some typos.
