Phpwiki cgi-system problem

I am trying to install a wiki on my site @ and I got the main page to load. But, when you click on any of the links it tries to look for it through “cgi-system/php.cgi” I can run the demo wiki @ just fine and I have looked in the configs and I cannot find out where the problem lies and how I should go about fixing it. Any help on how to get my phpwiki working would be great! Thanks!
