Chat window not appearing for non-admins!

Hiya.

I installed the Chat plugin on one of my sites, and configured it for registered members only. The bottom corner chat is showing up for me as an admin, but when I login as different subscriber test users, it doesn’t show up. I’ve gone to the “Authentication” area and enabled it for subscriber, but it’s still not working.

The subscribers can see and participate in a group chat that’s enabled. And as an admin, I can initiate a private chat with a subscriber, and THEN the bottom corner window will show for them. But the Public Chat room bottom corner window that should always be there is not showing for them. Also, when they go to a member profile or members directory, the button for initiating chat with someone doesn’t show.

Any help in solving this mystery would be greatly appreciated!!

Thanks.
