Question My Kunena Update - Kunena is not installed. Please contact site administrator.

Please help.
I have a problem and I don't know how to solve it.
In jomsocial I see the warning specified in the topic.
This issue had already been discussed in the forum, but without an explanation of the decision variants.
Thank you very much. Alexandr Stolbov

Of course it can be a bug as well.. Do other addons work?
