just updated from Matomo 3.4.1 to Matomo 4.0.1. Another update scenario was not given.
First of all, the update stuck because of an error saying something like
“mysqli statement execute error : duplicate entry” for key ‘primary’
I could solve this by going through the troubleshooting steps given in the updater: Increase the max_execution_size and memory_limit, followed by updating the “version_core” value to version “4.0.1” because still “3.4.1” was there.
Update was successful. But: When I try to login, all that happens is a “refresh” of the login page. I’m not sure if the login attempt is succeeded, I only see the login page.
Holy cow, I will now start my research through the forum. Let’s see what happens.
