Disable wp cron

When someone visits your wordpress website it fires off cron to check for updates.
This can slow the server down!

You can add the following to your wp-config.php

define('DISABLE_WP_CRON', 'true');

You do want wordpress to post or check for updates automatically so you should run cron via cPanel

cd /home/userna5/public_html; php -q wp-cron.php
