problems with posting messages

Suddenly I am no longer able to post messages in the forum with Firefox. The fields where you put the actual message have vanished. I'm using IE to write this and it looks quite strange in IE as well.Firefox screenshot: http://bildcentralen.se/images/2013/09/08/zDFX1.png

With Opera the post goes through but it gives out a warning saying that you can't post untin 30 secnds has passed.

Using IE and am having similar problems. It's a site issue.
