Cron not running when you expect? This plugin may help. Also provides insight into WP-Cron exactly like the Cron View plugin.
This plugin will visit your site every minute and thereby ensure that your cron jobs run on time. It is mostly intended for people who can’t use real cron for some reason.
Note: This is the exact same plugin that was previously sold on Code Canyon.
