I tried to help out with a suggestion. If you think you have configured your forum as you like it then let it be. The forum online box is only showing who is browsing adventures log. That's it and that's never gonna change in woltlab software
It is logic to show only the users browsing per forum. If you are in the overall forum landing page it shows everyone who is online that's the difference.
You could remove adventure log category and have the invisible forum still showing.
To me it's not logical to have a users online box that does not show all of the users online.
Also... did you not see that the box, users online, when displayed on a forum WILL show all of the users online if you click the link in the box to show the users.
That is not logical behavior. If it is only showing the members browsing a forum then why would it change to show all users when you clink on it's link?
To me it's simple. If there is a box that will show all the users online, then that's what it should do no matter where you feel like showing the box.
I guess someone could make a plugin, but that's really ridiculous.
Here is a common sense reason for wanting the box to show ALL users, even in a forum:
I want my users to be able to see all the people who are logged in.... wherever I decide to show it. Is it that hard to understand?
