Solved Bug? The main menu disappears

After installing the new version of Kunena 4.0.1, I have a problem very strange. The main menu of the website disappears, only when they are on the forum.
I have attached a video to better understand the problem.

I think I have a similar problem. In the "edit profile" menu, the different tabs (Avatar, User Account, ...) disappear (on crypsis template). Also the Kunena Menu disappears sometimes. I think it's some conflict with our joomla template. Which template are you using?

Hi Heinzo use a theme of YOOtheme. It is a real shame because I can not use more than the forum if you do not solve the problem.

I'm having the exact same problem after upgrading to Kunena v4.0.3 yesterday.

I'm using Joomla v3.4.1 and an up-to-date Yootheme template (Venice).

When you're in the Kunena forum, moving the mouse over the menu items makes any menu with a dropdown disappear, just like in the video posted by trench above. This only happens on Kunena pages and only since upgrading Kunena from v3 to v4. Very frustrating.

Is this a bug? Is there a fix?

UPDATE: This bug seems to only affect the "Blue Eagle" Kunena template. If I switch over to the other included template "Crypsis", this menu problem doesn't happen.

I'm fairly sure this is a bug with the way Kunena's Blue Eagle template renders in Joomla. I've only ever seen this problem once before and that was with a Release Candidate version of DocMan, which was fixed when the full version was later released and installed.

It shouldn't really matter what kind of forum template you use. The Kunena menu is just a Joomla menu.

There are a few ways someone can go about resolving problems with the Kunena menu. You could start by looking at the various sticky topics in the "questions" categories (except that the moderators here do not use the sticky topic feature these days), like this one: K 3.0 Kunena menu issues .

Alternatively, you could look in the FAQs page for help with the menu or elsewhere in the official documentation library (for example, Kunena menu issues ). 99% of these problems are usually solved with the trash-burn-build approach.
