You can see multiple messages which says :
I cannot send any message on forum without an xml parser error.
In fact they had been send and the first is the true question.
But as I got the popup message of an xml parse error and I have understood that it was the returned message of validation which was crashing Google Chrome.
what happens : when I try to send I get the “loading wait” animation. Then a popup window with the message error is displayed.
I uses Google Chrome and it seems that’s the returned message from the forum saying probably “message received” which creates the error.
It is impossible to know what had append if you don’t go back to the forum threads list.
You got all my tries… Sorry
