I've upgraded from version 1.6 to 1.8.21 and now arrowchat is not working anymore.
The chatbar is showing (in the left corner instead of the right corner) and it says Chat (0). After you click on it it changes to Chat (14) *the number people online*. If you click on a username nothing happens, so no new chat starts.
If you click 'Chat Rooms', the general chatroom opens but it's also too much to the left so you only see half of it.
It's a custom integration and uses the Arrowchat's push service.
Any ideas what could be the problem?
