Solved Kunena will not log in to site

I have used Kunena for quite some time. Recently I discovered that the users, though logged into the front end, are not logged into Kunena. Even entering the correct user/password does not work, nor does it work if I set guests to be able to post.



Here is my config info:

This is an issue that we have also. I have no idea of a fix.

try to disable cache, and then clean cache on joomla. And try again.
