Hi, I found out that Special:CreateWiki is now broken, with the following error displayed. Could you fix it? Thanks in advance :)
MediaWiki internal error.
Original exception: [9cdfadc7e2f6ed6060d19ce2] 2019-01-12 08:59:34: Fatal exception of type "UnexpectedValueException"
Exception caught inside exception handler.
Set $wgShowExceptionDetails = true; at the bottom of LocalSettings.php to show detailed debugging information.
The wiki does get created but the permissions are messed up, and the main page doesnt get created.
