I was a stupid fag and didn't back up anything before I went adding hacks.. I believe it was the whole Qasic Avatar thing, for it's the only hack I installed that deals with registering (and deleting things).
I added Avatar, Member Status, and the Last Reply. I've removed the Member Status and Last Reply hacks, and it still goofed, but I can't remove the Avatar hack, because I don't know where that stuff went that I deleted.
Either someone here can check my CGI, or I can reinstall the whole thing, but I'd RATHER go the first one first.. I hate installing CGI stuff.
