Bug in my Topic (Can't Edit my Own Topic)

Hello,

I Signaled the problem to Sun Tzu but the problem is still there.
Need Admin fix the bug to edit my main topic about my map.

Link of my topic - http://fr.atwar-game.com/forum/topic.php?topic_id=26232



Here an exemple when I clicked "edit", the topic is empty and i can't write something inside.


The problem from an broken picture (you can see just a small logo meaning the picture is broken in 1st line) seems made the bug.
So i think, if just delete this line it's ok, but not the topic please.
