Piwik seems not to store any further visitor-logs since an upgrade from Version 2.3.0 to 2.4.0 or 2.4.1.
I’ve already checked Piwik doesn’t track any visits and pages, and shows “There is no data for this report” in all reports. - Analytics Platform - Matomo and if there is an error with MySQL-Server.
I don’t have any errors in the logs.
The Image-Tracker is still able to request.
With the Plugin Live! I don’t see any incoming requests.
It is weired because I’ve got the same Installation for an other customer which has no problems.
