Since I updated to 3.13.2 I get the following message when I open the Administration tab: > WARNING: /var/www/matomo/core/Http.php(538): Notice - Trying to access array offset on value of type null - Matomo 3.13.4 - Please report this message in the Matomo forums: https://forum.matomo.org (please do a search first as it might have been reported already) (Module: Installation, Action: systemCheckPage, In CLI mode: false) I am currently running at 3.13.4. Also, my crontab for archiving doesn't work. I set it up as described in the documentation: https://matomo.org/docs/setup-auto-archiving/ Could that be linked to the warning message? I appreciate your help. Thanks in advance!
