Help: Sidebar Widget moves under new posts

I just recently switched over to a new host and I think something got messed up. I can log in and all my current posts are good, but now when I go to create a new post my whole widget bar moves to underneath the post and the header text sections of that widget bar have disappeared. As well the permalinks for post name have stopped working for new posts. Check out the post here http://lalords.com/307/ and you will see what I mean. Anyone please help! The main page and all other posts are ok. http://www.lalords.com
