This plugin hasn’t been tested with the latest three major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.

WP-Cron Control

Description

This plugin allows you to take control over the execution of cron jobs. It’s mainly useful for sites that either don’t get enough comments to ensure a frequent execution of wp-cron or for sites where the execution of cron via regular methods can cause race conditions resulting in multiple execution of wp-cron at the same time. It can also help when you run into posts that missed their schedule.

This plugin implements a secret parameter and ensures that cron jobs are only executed when this parameter is existing.

Limitations

This plugin performs a remove_action( 'sanitize_comment_cookies', 'wp_cron' ); call in order to disable the spawning of new cron processes via the regular WordPress method. If wp_cron is hooked in an other action or called directly this might cause trouble.

  • If you like to have a global secret string you can define it in your wp-config.php by adding define( 'WP_CRON_CONTROL_SECRET', my_secret_string' );

This sometimes works. Unfortunately, if you have any questions about it or issues with it, you won't hear back from the devs 🙁 In my experience, it does not work in WP multisite 5.2.1 if you are trying to trigger the cron via the PHP command. The wget command seems to work fine, but the best part of this plugin was to allow it to trigger through the PHP server.
