How to replace wp-cron with cron job without WP Toolkit

Introduction

WordPress's wp-cron is not a real cron job. A cron job runs at a specified time or interval, while wp-cron runs when the page is loaded. This can cause low-traffic sites to miss scheduled posts. Creating a cronjob to run wp-cron will ensure that scheduled posts are not missed regardless of site traffic.

Procedure

1. Open the site's wp-config.php file in a text editor.
2. Add the following line after the <?php line.

   define('DISABLE_WP_CRON', true);

3. Save the changes and close the text editor.
4. Log into the user's cPanel account.
5. Open the "Cron Jobs" application in the "Advanced" section of cPanel.
6. Create a new cron job that runs the following command every 15 minutes.

   wget -q -O - http://domain.tld/wp-cron.php?doing_wp_cron >/dev/null 2>&1

   Please note that "domain.tld" must be replaced with the site's domain name.
