Thread:Project:Support desk/MediaWiki 1.20 internal error (2)

I need some help here...

I contacted our web host and they said that the htaccess file needs to be modified, but they didn't have information on how it had to be modified.

I don't know what to change in it to get this to work...any ideas? I've looked all over and have not been able to find an answer.
