Plesk Web Admin Edition running Blesta run every 5 min
Tools Settings / Scheduled Tasks (create new Cron Job)
/opt/psa/admin/bin/php -q/var/www/vhosts/YourDomain.xxx/httpdocs/index.php cron > /dev/null 2>&1
(Make sure there is “no” space between the php -q and /var as noted above)
(above assumes default location of public files httpdocs)
(Your location of php may vary depending on your hosting provider, or server install)
Use Cron Style for the "Run" : */5 * * * *
Will setup for every 5 min, every day, 365 days per year
Apply and Run (for test) should execute with green success pop up.
