UBB.Developers Forums UBB.classic V6 Mod Questions Not really a mod question, but help:)

FIRST OFF LET ,ME APOLOGIZE IF THIS IN THE WRONG FORUM OK? (And lets face it, I probably have an iq of 25. )

But anyway, I have 6.1.0 PB 1.4, and being the fiddling person I am in the cp, I decided to go to ubb upgrade and click the button.....now all the time it says:

FYI

Could not find any forum_thread_data files! Please tell the board administrator to Rebuild Forum Stat Files for forum: 21

» Please use your browser's back button to return.

This continues to happen. Can you help me out? Have I set something up wrong, and I KNOW ALREADY THAT PRESSING THE BUTTON WAS WRONG!

Will I need to re-install the boards or what?

and yes I have pressed Rebuild Forum Stats or whatever numerous times....

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.
