It was only a temporary fix. The problem has come back again.
Instead of uploading the one js file, I uploaded all of them to the xf folder in the js folder. This fixed the formatting problem again, but when I came back all of the icons returned to their funny position.
No, the website is fine, it's just that the rectangular "thread title" box above the threads in each subforum leaves the formatting options in that funny position every time you try to start a new thread.
