Bad HTTP_REFERER!!

Hi.  I just installed PunBB.  My forums are at http://www.chaosgamers.com/forums and I cannot update anything in the admin section because of Bad HTTP_REFERER.  I set my base URL to http://chaosgamers.com/forums.  I don't get whats wrong!!  I love your script, but if this problem doesn't get solved then I'll have to switch

Edit: My forums says it's closed, but it's still there.  I have an index.html page because its down for matanence.
