Unable to run CRON for scheduled jobs in Drupal 7.43 and Civicrm 4.7.7
You need to set a cron command on the server.

https://wiki.civicrm.org/confluence/display/CRMDOC/Managing+Scheduled+Jobs

Something like

*/15 * * * * wget -O - -q -t 1 'http://mysite.org/sites/all/modules/civicrm/bin/cron.php?name=username&amp;pass=password&amp;key=site-key'


If you have set it, what is the exact cron command for CiviCRM you have set on the server (cpanel, directadmin ....)? (You can leave out the pwd)
