How to run triggerRebuild URL
Sorry for the too terse explanation you received on the other answer, using a shortform that experts are used to. If you are running a Drupal site, example.com, then to rebuild your triggers navigate in your browser (by pasting in the url) to http://example.com/civicrm/menu/rebuild?reset=1&amp;triggerRebuild=1 , for WordPress it is http://example.com/wp-admin/admin.php?page=CiviCRM&amp;q=civicrm%2Fmenu%2Frebuild%3Freset%3D1&amp;triggerRebuild=1 , and for Joomla it is https://example.com/administrator/?option=com_civicrm&amp;task=civicrm/menu/rebuild?reset=1&amp;triggerRebuild=1. 

Without a reference to your earlier question, I'm not sure which version of CiviCRM you are running. FWIW, I think this fixup may have changed in recent versions. 

Make sure you have admin CiviCRM permissions.
