I'm having some strange behavior that started today. Installed over a week ago with no problems, but this afternoon, none of the blocks on the Right column are showing up. I move a block, say current users, to the Left block and it appears but not on the right. Some blocks have stopped showing up no matter what column. The rest of the forum is working just fine.

I re-uploaded all the module PHPs and index file, still no love.
Tried adjusting usergroup permissions, still no love.
Optimized/repaired tables, still no love.

Any suggestions would be helpful.
