Stick / Unstick no longer working - just getting a blank page. Any ideas?

I have a few hacks installed. I just noticed though that when I try to stick a thread, I just get a blank screen, and it doesn't work. I don't know how long this has been going on. Anyone else ever encountered this?

Hacks I have installed:
- Admin Quick Stats
- Send default PM to new users - templated
- Admins can view User PMs
(perhaps 1 or 2 more - I can't remember)

Actually, now that I check, the only Admin Options that do work are Open/Close thread and Edit thread.

What's not working:
Stick/Unstick
Move/Copy
Delete Thread/Posts
Merge Threads
Split Thread

ANY IDEAS? Thanks!

reupload an unhacked posting.php

then redo the hack, but carefully!

also if this doesn't help, maybe your showthread template is corupted (the adminoptions section)

Thanks for the suggestions. I had previously changed the "showthread_adminoptions" template to move from a "drop down" to "links." So, I reverted the template to the original, and that solved everything. Thanks again for helping out. Your suggestions led me to figuring out what was wrong.
