Wow, I see many problems with your UBB you might want to consider upgrading and completely re-installing your cgi-bin and templates.
1. No Post Topic or Post reply images(you can just upload those)
2. Avatars and Star images are broken.
3. I agree and Cancel buttons do not show up properly on registration page.
4. Chat does not work.
5. Out dated who's online(many many bugs fixed since your version)
I would just suggest re-installing and re-hacking your board. It will not take that long.
