121291 PHP Script Error, MySQL glitch

I have a photo battle script running perfectly at [login to view URL] and the same identical one at [login to view URL] however the one at [login to view URL] will not let me see the profiles if I click on the thumbnails. The profiles are there, and I can see them in the database after creating them, but they just want come up and I get a "No Such Profile" message. Both scripts started with the exact database structure, therefore I can not figure out the problem. The scripts are on seperate servers so I don't know if that has anything to do with it. Please bid if you think you can help. I also require a detailed explaination of what the problem was and how to solve it in case I run into it again.
