Hello friends, some time ago I was told that if I place a file at /var/www/"anything" at the DocumentRoot it will be as my index file. Now, I installed the MediaWiki and I place the DocumentRoot like this and I restarted Apache:

/var/www/mwiki1.7.1

And I get this error:

Not Found
The requested URL /mwiki1.7.1/index.php/Main_Page was not found on this server.
--------------------------------------------------------------------------------

Apache/2.0.55 (Ubuntu) PHP/5.1.2 Server at 10.0.3.107 Port 80

I tried this with a CMS called Jupiter and it worked fine. I not sure if this error has to do with MediaWiki.

Thanks...

This is a configuration error with your CMS. For whatever reason, Apache is processing the full request (/index.php/Main_Page), but it should only be processing the index.php. MediaWiki should be processing the Main_Page directive. Check your CMS.

Thanks cdhgee, but I don't know what should I be checking for in my CMS?

I've never used MediaWiki so I can't advise you on that I'm afraid. You might try re-reading the documentation on how you integrate it with Apache, that might give you some ideas.
