If you're using Devel module then you can simply go to your-site/devel/php and then execute the below code:

actions_synchronize(actions_list(), TRUE); 

or else in any of your custom module's .install file write an hook_update_n()

/** * Implements hook_update_n(). * actions_synchronize(). */ function yourmodule_update_7001() { actions_synchronize(actions_list(), TRUE); } 

and then execute yoursite/update.php or if your're using drush then drush updb

If you're using Devel module then you can simply go to your-site/devel/php and then execute the below code:

actions_synchronize(TRUE); 

Your question indicates you have drush so you could evaluate the command with that;

drush eval 'actions_synchronize(TRUE)'

If you need to do this on a remote install where you don't have access to drush you can add this to a custom module's .install file with a hook_update_n()

/** * Implements hook_update_n(). * actions_synchronize(). */ function yourmodule_update_7001() { actions_synchronize(TRUE); } 

and then execute yoursite/update.php. You can test this locally using drush updb as well.
