Who's Online Details Missing for Registered Users?
 

I have an oddity occurring on my board...

The Who's online page (online.php) shows all the correct details for guests, such as what thread they are viewing, etc. However, I am only able to see certain information for logged in users, such as viewing attachments, if they are in the arcade, using chat, or replying to a thread. For some reason, I am unable to see what thread a registered user is viewing. It either shows the statuses I just mentioned or shows them viewing the index, even when they are looking at a thread. I've tested this several times with no avail. I've checked all the usergroup permissions and even compared them to similar boards and I can't seem to identify why this one piece will not work properly. I remember this working fine before, but I don't know where to begin since it works for guests but only "halfway" for logged in users. I hope I am making sense.

Any ideas?
