Evidently there is a huge problem with wp-cron being spawned multiple times which will overload your server.
DISBALE wp CRON in wp-config.php:
- Open your wp-config.php
- Add next code:
define('DISABLE_WP_CRON', 'true');
- Save your wp-config.php file
Now, Go to your cpanel account and add CPANEL cron:
- click on Cron Jobs.
- under section Add New Cron Job Select Once an hour from the Common Settings drop-down
- In the field Command fill in next code to run our cron job and click Add New Cron Job
wget -q -O - http://yourwebsite.com/wp-cron.php?doing_wp_cron >/dev/null 2>&1
It is highly recommended running wp-cron via crontab rather than WordPress’s default way, especially for sites with high traffic.
