Account Integration

I am trying to get the WordPress / BuddyPress account integration working. I have followed the instructions on the API page and installed the plugin.

The chat room appears, but says “This chat-room is for private users only” This happens regardless of if a user is logged in or not to the site.

I have made sure in the RumbleTalk settings page that Allow login as Guest is checked as per the documentation.

Any advice would be appreciated.
