I have newly installed ISPConfig Version: 3.0.2.1. When I want to start new cron job for a new site , cron job is not starting, and I have read that error message in cron logfile: mkdir: cannot create directory `/var/www/clients/client1/web1/var': File exists mkdir: cannot create directory `/var/www/clients/client1/web1/var/run': File exists usermod: no changes usermod: unlocking the user would result in a passwordless account. You should set a password with usermod -p to unlock this user account. What that mean ?
