Cacti logfile access error after upgrade Stretch -> Buster
after upgrading from Debian Stretch (cacti 0.8.x) to Buster (cacti 1.2.x), I can't access the cacti web ui anymore. I only get a message "System log file is not available for writing, please enable write access
Log: /usr/share/cacti/site/log/cacti.log" in the browser.
Am I missing some upgrade steps here?
