Well, Crispy, I seem to have the same problem from another angle, and it does not seem to be a matter of confusion.
Preparing my new site based on DNN 5.1.2, I happily upgraded it to the latest Forum 4.5.3. Obviously, there have been some major improvements which I like. Yet, some basic functionality seems to have been lost (or I am just not able to find how it is done at this Forum 4.5.3 level):
On one of my pages, I've got a Forum module with 4 forum groups, two of them public and two private with posting restrictions. I also have the Aggregate Forum.
It all worked fine with the previous Forum 4.4.3 release. I set the forum configuration rules based on roles, who can see what, who can start new threads, who can reply. And the Aggregate Forum correctly showed the public forum threads only.
After upgrading to the new Forum 4.5.3 level, my Aggregate forum is mixed up and shows threads of the private forums, which it should not.
I like the new Forum Control Panel and the way it works, yet I am absolutely not able to find the Forum Configuration where I can control the forum type (public/private) and user permissions. I tried everything I could possibly think of, without success. The Configuration seems to have been dropped out.
The icons next to my forum groups still display correctly as public or private, but the Aggregate forum seems to ignore that. And I can not find the way to check/control the settings.
If the problem is with me, please help. I am certain others will benefit from a bit of guidance too.
And, if this is a real bug, I expect you will fix it promptly with a new release. Yet, if that is to take more than one-two weeks, should I go back to the previous Forum 4.4.3 level? I would appreciate your best suggestion.
Thank you.
