Question Getting strange errors on Kunena

Tried that still getting an error
Error
Duplicate entry '0' for key 'PRIMARY'

Is the Error Reporting set to maximum in the Joomla site as well?
latest joomla version is 3.10.10. And sometimes also helps with Extensions: Update Sites right at number to everything and then check the box on the left to select everything and then click rebuild. after that click on update extensions clear cache and on new search to make sure everything is up to date
the problem with the website is that with a hoster or is it at a local server like Wamp or Xampp.
And do you sometimes use extra extensions or plug-ins such as JCH optimizer.
sometimes it can help if you also include your Report Configuration

Wow, I had the opposite experience. None of my sites would upgrade through Joomla. I have spent the last 3 months rebuilding dozens of client sites from scratch in Joomla 4. The biggest issue is the mandatory images directory. I used a custom user data folder for all of my sites, and the mandatory image directory basically broke all of my websites. Also my third party extensions didn't all come up at the same time so the automatic updates never worked for me.
