I just recently downgraded my phpnuke to version 7.6 from 7.8 and my theme is giving me a small problem. Now on my new site, the left and right side border does not appear on FireFox, but on IE it appears just as it should. It seems to appear at first (right as you load the page), but then the main content stretches out and the borders disappear. I've tried comparing the two html sources and have not been able to diagnose the problem.

http://old.novclan.com (old site, border works fine)
Any and all help is very much appreciated. Thanks folks!
