All of a sudden the blocks I had on the forum have started showing up at the bottom of the forum instead of to the right! When I go to add blocks to the right there is no place to add them.

Have the templates been edited or changed at all? Only reason this could/would happen.

Quick edit: is it also occurring on the default theme?

You may have put in a block, or in global template code without the  "}"

Share a link to a site and someone will easily find the error.

I have not messed with any of that cause I do not know what I am doing when it comes to that...I got one other thing I will try and get back to this thread shortly.

OK...I had placed an Advertisement below the header, I removed it and things went back to the way they were...I don't know what the Advertisement had to do with it.

Check the advertisement code. It's likely a missed closed bracket.
