MyBB Community Forums

So, I've noticed that the name of threads are messed up - Example if I go in to a thread called "Hello" it would show up a different name of another thread that exists on the forums - What could be the cause of this?

And polls are not working, when you click on vote it just takes you to a blank page that does not load.

Thanks in advance,

EDIT:
I solved the threads name issue, advanced sidebox was causing that to happen for some reason. I disabled the plugin.
