help please!! threads disappeared!!

[salata]

i was installing the vbspace hack, and my threads dissapeared. when at the index page you can see the last thread that was posted and when you click it you can still view that thread. but when you try and go into the forum, it displays no threads. but it says that there are pages of threads when you look in the top corner. why are my threads hidden? also when you click "new posts" in the nav bar, threads show up but now when you click on the forum. global announcements are still viewable, but no threads.
