This is a misconfiguration issue, not a Cacti issue. This tracker is for Cacti bugs. Please continue this support discussion on the Cacti Forums @ https://forums.cacti.net

Just from a quick look, the Cacti Troubleshooter says your webserver is using the "www-data" user, but your cron is for the "apache" user.
