Simply copying the footer isn't enough. The forums and your home page run on two differant style sheets and both use differant software, Wordpress and vBulletin.
Well we have pulled the code from the site, which is how we implemented it on the portal (which worked fine). I'm not understanding how there can be errors in it when the header is working flawlessly, and that's what we did for that as well. If need be I can paste the footer HTML code here or you can view it via your browser. I've tried everything. I'm not sure where the error is. What's bad is it's most likely something very small :P
