The message you have entered is too short. ? Err, no it isn't!

[archet1337]

When posting using the quick reply I get this message even when posting several sentences:

"The message you have entered is too short. Please lengthen your message to at least 3 characters."

When I click the back button in the browser and submit again it works. But this is really annoying.

Firebug also show the following error on the showthread page:

Syntax error - vbulletin_quick_reply.js

ass("qr_error_tbody","hidden");vB_Edit...;return false}}var vB_QuickReply=true;
