Disabling WP-Cron and using a real cron job

WordPress has a built-in task scheduler called WP-Cron that handles scheduled events such as publishing posts, sending emails, checking for updates, and running plugin tasks. However, WP-Cron only runs when someone visits your site — it is not a true cron job. This means scheduled tasks can be delayed or missed entirely on low-traffic sites.

Replacing WP-Cron with a real server-side cron job ensures your scheduled tasks run reliably and on time. It also removes the small overhead of checking for due tasks on every page load, which can slightly improve performance.

Step 1: Disable WP-Cron

Log in to cPanel and search for File Manager:
Navigate to the document root for your WordPress site (typically public_html), right-click wp-config.php, and select Edit:
Add the following line above the line that reads /* That's all, stop editing! Happy publishing. */:
```
define( 'DISABLE_WP_CRON', true );
```
Click Save Changes in the top-right corner of the editor.

Step 2: Create a cron job in cPanel

In cPanel, search for Cron Jobs and open it:
Under Add New Cron Job, select a schedule from the Common Settings dropdown. Once Per Hour (0 * * * *) is a good default for most sites. Sites that depend on more precise scheduling (e.g., time-sensitive emails or frequent post publishing) can use Twice Per Hour or Every 15 Minutes instead.
In the Command field, enter:
Terminal window
```
wget -q -O /dev/null https://yourdomain.com/wp-cron.php
```
Replace https://yourdomain.com with your actual domain. The -q flag silences output and -O /dev/null discards the response so it does not accumulate in your hosting account.
Tip
If your site is behind HTTP authentication or you prefer not to use an HTTP request, you can call wp-cron directly via PHP instead:
Terminal window
php /home/username/public_html/wp-cron.php
Replace /home/username/public_html/ with the actual path to your WordPress installation. You can find this path in cPanel under File Manager or by checking the Home Directory shown at the top of cPanel.
Click Add New Cron Job to save. The new cron job will appear under Current Cron Jobs:

Verifying it works

After setting up the cron job, confirm that WordPress scheduled tasks are still running correctly:

Scheduled posts should publish on time without requiring a site visit.
In the WordPress admin dashboard, plugins that rely on WP-Cron (such as backup or email plugins) should continue to run on schedule.
If you use the WP-Crontrol plugin, you can view all scheduled events and confirm they are firing as expected.
