Solved Kunena menu problems: menu disappeared after updating Joomla 3.3.6

no, sry.
When you go to the kunena forum in frontend. Than there are the topics and above the possibility to login for members. And above that I formerly had three Tabs. Me and members could klick on "current" (or named similar - in german it was "Aktuelles") and there they could see only the newer entries.
If you go in backend to kunena -> configuration -> frontend you can declare that the current entries could be defined as "the last month" or "since last visit"...
But in frontend I cannot click this current view (sry for my english ).

if you have installed the kunena language pack, then go to backend - kunena - tools - menu manager - click on restore menu.

Then the menu is german again.

I am really sorry, but the language is perfect!
The tabs are missing. So you cannot look at the current entries.

But this is not the biggest problem. As I wanted to do your last tipp, I realised, that all the links are failing.
The categories in the mainpage from kunena are still there. In the right column the numbers of the posts are still correct. But when I click on a category, I get an 404 error "category not found"
The menu manager said: no mistakes. The click on restore menu was no help.

Sorry for the next problem
I have to leave now, but I will return tomorrow! Thank you very much for your help till now!

ok, paste tomorrow the kunena report.

backend - kunena - tools - report

Here it comes:
