Siropu,
The version of the Chat is 2.1.3 I'm using most recent XenForo v2.1.5.
I disabled rooms completely, made it put ppl in the general chit-chat room. When new users register on the forum they see a blank chatbox and it says "You're not in any rooms" and there's no option to join any rooms (probably because rooms are disabled). But nonetheless, I've even tried having the rooms enabled, and still they can't see a way to join into any active rooms. I checked permissions for registered users and they are all set to be able to see and use the chat.
What I noticed (This is a strange observation):
I registered a new name on my forum and one time that new user was placed into a room automatically. I then proceeded to register a new name once more, and then once again that user was placed into a room upon login as a brand new user. However, on my 3rd attempt I saw the message about not being in a room and then this went on randomly. Some new users get placed, some new users don't. Some existing veteran users were being placed... while some were not getting placed in a room. I wish I had more direct information, but so far I can't figure out what's causing the issues. Permissions? I've checked these too.
