How this can be fixed? or this is something that I did wrong?

Strange thing is that I get this error if I start the chat in google chrome and then join with another user from firefox. But if I start from google chrome and join also from chrome then it's working...

all right, now the problem is with firefox? I restarted the server and try to conect to chat as admin (first user in chat) and it's shutting dow. is there a bug with firefox?

In Opera the join button isn't working
