Need HELP Please, when i type in a category this is what I get:
 
The requested URL /Arts___Humanities/ was not found on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

Sorry, but it is not clear from your question, where do you type category. Is this known PHP script or custom made? Provide as much details as possible.

When I click on the category from the main site. I was just doing a test of the site and clicked on a category, and that is what i received?

What is the address of the MAIN site? And what category you clicked there?
