Thread:Project:Support desk/Special:Upload not found

Mediawiki - 1.16 PHP - 5.2  MySQL - 5.1

I just installed mediawiki onto my forum using my host's one-click install feature. Everything seems to be working great and I was looking into how to do uploads. However, there is no "Upload File" option in the toolbox. I tried to go directly to Special:Upload, but I'm getting a Not Found Error. It's also not listed in the special pages. I activated file uploads in the LocalSettings.php.

URL: http://markedrp.com/w/Special:Upload

Error: Not Found

The requested URL /w/Special:Upload was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
