Hello @mononym
I have investigated this issue and found the following.
According to my understanding after reading the documentation the LocalSettings.php should include the following:
# Set the script path to root
$wgScriptPath = "";
# Set the article path for pretty URLs
$wgArticlePath = "/$1";
# If you're using a different entry point than index.php
$wgScript = "/index.php";
# For resource loading
$wgResourceBasePath = $wgScriptPath;
Just for good measure I also cleared the Main Page cache with:
php maintenance/run.php purgePage <<< "Main Page"
But sadly, this did also not work.
So the only thing now breaking it could be the apache2 config and there it is.
By default (not editable) - https://git.cloudron.io/packages/mediawiki-app/-/blob/master/apache/mediawiki.conf?ref_type=heads:
ServerName %{HTTP_HOST}
<VirtualHost *:8000>
DocumentRoot /app/code
LogFormat "%{X-Forwarded-For}i %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" proxy
CustomLog "|/bin/cat" proxy
ErrorLog "|/bin/cat"
# https://www.mediawiki.org/wiki/Manual:Security
php_flag register_globals off

RewriteRule ^/*$ %{DOCUMENT_ROOT}/index.php [L]
<Directory /app/code>

</Directory>
# some directories must be protected

<Directory /app/code/images>
Options -FollowSymLinks
AllowOverride None
<IfModule mod_php7.c>
php_admin_flag engine off
</IfModule>
</Directory>
</VirtualHost>
I put the app into recovery mode and edited the Apache2 site file and changed the rewrite to the following:
RewriteEngine On
RewriteCond %{REQUEST_URI} !^/rest\.php
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} !-f
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} !-d
RewriteRule ^(.*)$ %{DOCUMENT_ROOT}/index.php [L]
and started the app with /app/pkg/start.sh and got a working MediaWiki under sub.DOMAIN.tld/Main_Page.
To make this usable for you and everyone else, an app update would be needed where users, like you, could also upload a custom Apache2 site setting file that will be included to overwrite the default one.
I am converting / hijacking this topic into a feature request.
