Ok, backup job moved to 1am, and my bulk delete job did not run at 2am – wp-cron was executed, according to email notifications.
The scheduled job disappeared from the control panel list.
Here is the options array after I re-scheduled the delete job:
Array ( [0] => Array ( [selected_types] => Array ( [0] => cars-publish [1] => photos-publish [2] => option-publish ) [restrict] => [limit_to] => 0 [force_delete] => 1 [date_op] => [days] => 0 ) )
I want this to run daily – is the [days] => 0 correct?
