We are having the same issue where we cannot delete cron jobs that have these characteristics:
- Our custom PHP cron events
- The Next Run date has already past
- The time is appended with (now)
- Modifying the date or frequency creates another cron job
We deactivated/activated WP Cron, then tried to delete one of these cron jobs. This message is displayed:
Successfully deleted the cron event crontrol_cron_job.
But, it is still listed.
Please help.
