Catagory Display Error

[Guest]

Hi,

 

I installed osCommerce for a client of mine and it's perfect...

http://kostasphotoproductions.com/catalog/

 

But it won't display the catagory pages. It gives me the error below:

 

Error!

 

Unable to determine the page link!

 

 

I don't know what's wrong with it. An installation error? Didn't chmod a file? I went over the installation in the docs a few times and still couldn't find the error. Everything else works perfectly.

 

Little help here?
