Crapola...it's done it again. Here's *exactly* what I did...
Went into the control panel, to the forum settings page, unchecked a single "enabled" box next to a single forum, and "Whammo", when the forum settings box refreshes it says you have no forums. If you go to the past 24 hours link all the posts/threads are still there, as are the forums, but they won't show up on the main page.
Oh, and this *might* be a sub-forum, enabled from an old Sub-forums hack...
Any ideas, other than the w3t_Forums suggestion above? Please??
