a couple of days ago I did an automatic update to Matomo 4.0.2. That resulted in a hosed database. This was probably my fault beca<use I did not see that I was supposed to delete some files.
The db is fixed now and I can log back into Matomo (https://linuxnews.de/piwik/), but I get an error that I don’t understand what I need to do. I attached a screenshot
Thanks for any pointers!
