I want to create a forum with 3 main topics:
1/ Books (new container)
2/ General Discussion (already created as forum, not container)
3/ Music (another new container)
I don't want users to create a fourth topic at the root level.
My understanding is that the three root topics should be containers but somehow, it doesn't work.
When creating a new topic in Books container, I am getting the following error:
The item Books is a forum container, not a forum. Select one of the forums below instead.
