Thank you very much for your prompt answer. I checked the website again and it looks for me pretty simple, no complexity. That is to say Cassiopeia template as default with modifications in user.css (pictures, background, colors ..). The CB template is on default. There are no 3rd party templates. I checked the updates and tried to update to the last version and I receive a new error:
System Information
Joomla: 4.2.8
PHP: 8.0.28
Database: mysql 10.4.28-MariaDB
Package
File: 000_pkg_communitybuilder_2.8.0+build.2023.02.27.16.27.04.78b0b77aa.zip
Log:
Code:
<div>Duplicate entry '8' for key 'PRIMARY'</div><div>Paket Update: Bei der Installation der Erweiterung trat ein Fehler auf: com_comprofiler.zip</div>
I have no idea where to search for this error, at least I couldn't find any duplicates.
What will happen, if I deinstall Community Builder an reinstall it? Will we loose all User Data? How could we migrate the users to a new environment? We checked Community Builder on a test site and it works ok.
Regards
Jürgen
