At the moment URLs are like this:
https://pietro.pensa.it/mediawiki/index.php
But they should be like this, really:
https://pietro.pensa.it/w/index.php
Current htaccess:
```
RewriteEngine on
# Don't rewrite requests for files in MediaWiki subdirectories,
# MediaWiki PHP files, HTTP error documents, favicon.ico, or robots.txt
RewriteCond %{REQUEST_URI} !^/(stylesheets|images|skins)/
RewriteCond %{REQUEST_URI} !^/(redirect|texvc|index).php
RewriteCond %{REQUEST_URI} !^/error/(40(1|3|4)|500).html
RewriteCond %{REQUEST_URI} !^/favicon.ico
RewriteCond %{REQUEST_URI} !^/robots.txt
# include these last two lines if you use the analog stats
RewriteCond %{REQUEST_URI} !^/failed_auth.html$
RewriteCond %{REQUEST_URI} !^/missing.html$
RewriteCond %{REQUEST_URI} !^/stats/
RewriteCond %{REQUEST_URI} !^/mediawiki/
RewriteRule ^(.*)$ mediawiki/index.php?title=$1 [QSA]
