Question no recent discussions, no my discussions

Hi,
I installed the kunena 1.0.9 in my website and I made some categories, etc

My problem is that in the recent discussions or in my discussions doesnt show anything.

I checked in the kunena configuration but everything I think that's ok there.
Do you know what the problem is?

No. You haven't given any other information except that it isn't working.

The main forum is a CATEGORY. You can not post in a Category, it is only a container for Forums.

So every forum needs at least 1 parent (=category).

Please build a new Forum in Main "forum" in Kunena Backend -> Forum Administration.

Don't forget to publish it and to set the correct permissions.
