Provide a valid link to your board... and you might want to consider re-uploading the cgi-bin files, especially ubb_registration.cgi. See if that works, and if you need further assistance please ask.
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.
