I tried to configure Page Chat to appear to all of my wordpress users, and not to the public. I added the chat shortcode to my page http://mohabat.co/live-chat/ but it's not appearing to my wordpress "subscribers". If I make the chat available to the Public, then my wordpress subscribers do see it, but that's not what I want. I've tried creating a few new wordpress users to see if there was a problem with one of my test users.
I don't want site-wide chat, but I experienced the same issue there, my wordpress subscribers didn't see the corner chat window unless I made it available to the public.
My admin user can always see the chat window, but I wish my subscribers could see it too.
I did increase the wordpress memory limit in wp-config, as instructed.
I'm very open to being shown where I miss configured the settings. At this point, I've tried everything I can think of.
I've granted Support Access in the WPMU Dev dashboard. You are welcome to create new users if you need to in order to test the user-only chat authentication. This site is in early development.
Also, could you help me understand how to start a private chat? When I'm in a public chat window on my site, I've tried sending chats to @user, but they still seem to be visible to all of the other public users.
