I have a few mods on my live copy of Threads (6.3) like IIP and Quick Reply. I wanted to start working on a new template set (:)) and a couple other mods, without affecting the live copy until they're finished. So, I installed a new copy onto my localhost server, then replaced the localhost php files with the live server ones (except the three .inc's that aren't supposed to get overwritten). Then, on the live server, I backed up the database, downloaded the .sql files and restored the localhost db from them.
Everything seems to work... except forums. When I go to my localhost copy, everything shows up just like I want it to, except there are no forums and no categories displayed. The forums and categories are technically there, because I can edit them in the admin section and stuff. And if I make a new forum, it shows up. But the forums from the live site backups don't show up at all.
Anything I can do to fix this?
Thanks much.
