from your image I can see that you use some hack, it is not original Kunena setting for access, do you maybe using Duch modified Kunena version, if so, ask for help who are made a hack or install original Kunena file and check if you still have problem.
I have actually just run into this problem. All the settings are right for public access and yet when clicking on the the forum, you're asked to log in. Any solution for this yet?
Here is the solution to my problem, maybe it will help.
I had a link to the forum on 2 menus.
One was on the Main Menu and could be seen by the public. When that link was used, you still got "Please Log In" message when you clicked on a forum topic even though it should have been a public thread/forum.
The Other link to the Forum was on the "User Menu" and the Access level was set to Registered. I set the access level to Public and everything was fine.
