UBB.threads PHP Forum Software Community Forums UBB.classic UBB.classic 6 Support Can't Create Catagories

When I want to add Catagories and I hit add catagory it redirects me to a 400 Bad Request page. And I did enable that catagories are allowed. What's wrong?

Moving to UBB6 PIT for future followups...

It is difficult, if not completely impossible to properly diagnose most UBB problems without knowing which version of the UBB you are using, as well as the FULL URL to your ultimatebb.cgi file, (NOT a link to your webpage). Please provide this information. Thanks. <img src="https://www.ubbcentral.com/boards/images/graemlins/smile.gif" alt="" />
