I have Apache Error coming from /wp-cron.php. I didn't modify that file. How can I avoid the timeout?
WordPress uses a file called wp-cron.php as a virtual cron job, or scheduled task in order to automate things like publishing scheduled posts, checking for plugin or theme updates, sending email notifications and more.
By default WordPress is setup to call wp-cron.php everytime someone visits your WordPress website when a scheduled task is present, to basically ask "is it time to do anything yet?".
On low traffic sites this is perfectly fine, but when visitors roll in, checking multiple times for scheduled tasks can be very inefficient and lead to resource usage problems for your server, plus make your website load slower.
Disable default wp-cron.php behavior
We can easily tell WordPress to let us handle the execution of wp-cron.php with the wp-config.php file.
Open your wp-config.php file with the cPanel File Manager Code Editor Go to the bottom of the database settings in wp-config.php typically around line 37.
Add the code below :
Setup manual cron job for wp-cron.php
We don't want to leave WordPress without any ability to automate tasks it might need to do. But at least now that it's not running for every single visitor, we can have way more control over when these tasks take place.
For most WordPress users having the wp-cron.php script run every 6 hours is perfectly fine. That would be just 4 executions in a day, compared to possibly hundreds, or even thousands if you had a lot of website traffic that day.
- Log into cPanel
- Under the Advanced section, click on Cron Jobs.
- Select Once an hour from the Common Settings drop-down.
- Now select Every 6 hours from the Hour drop-down.
Finally fill in the code to run our cron job and click Add New Cron Job.
- cd /home/userna5/public_html; php -q wp-cron.php
Where userna5 is your cPanel user name.
Keep in mind that the /home/userna5/public_html path would be for a primary domain, if you're using an addon domain, or have WordPress installed in a sub-directory you'll want to be sure to update your path.
You should see that your new cron job was added successfully.
