Hi Beat - in order to avoid poking in the fog I have analyzed after which step the 'problems' will occur. So I have done the following steps:
1. I have cleaned up the whole website instance and freshly installed an 'old' image / backup of my website
The installed version of CB was CB 2.6.2 & Joomla 3.10.0
2. I have tested if there are any issues conerning menus and / or CB menus --> result: everything works 100% perfect
3. Now I have installed the following CB package: pkg_communitybuilder_2.6.4+2021.11.03.13.53.07.9ce3e2109
4. I have tested again and now there are 'weird' inconsistencies - Please have a look at the following screenshot:
Behaviour after step 4: If I click on the (CB)menu link 'User search' (number 1) ......then the (correct) list of users will be visible (number 2) ....but the problem is that also the menu links 'Block User' / 'Send Private Message' / 'Add Favourite' are visible (number 3) ...but this makes no sense because I didn't select a certain user from the visible user list.
Conclusion: I didn't touch the menu or the menu settings. The only step I made was to load this CB package .....question: is it possible that this upgrade 'deleted' a certain setting in my website somewhere? At the moment I have absolutely no clue where to find the bug .... I think the problem is not a wrong menu or cb menu architecture ... Please help me
PS: The underlying module type of this Community Menu is: 'CB Content'
