1) – In /lib/plugin-update/plugin-update-checker.php uncomment line 1296 wp_schedule_event(time(), $scheduleName, $this->cronHook); add return;
2) – Install WP Crontrol by John Blackbourn & crontributors
3) – Go to yourdomain.com/wp-admin/tools.php?page=crontrol_admin_manage_page and delete the pp_important_messages3 hook
I already deleted “pp_important_messages3” before the send the first forum message. Only problem “check_plugin_updates-hide-my-wp”. I delete this cron but it keeps coming back. I could not delete it permanently.
