This week we saw WordPress roll out version 4.0.1, which was a incremental security update. Normally, these incremental updates do not cause much harm, but today was different. We saw numerous plugins and themes that broke because of the update.
If you want to turn off WordPress core auto updates so you have more control over how and when your site is updated, follow the steps below:
1. Open your wp-config.php file
You will find this in your hosting file manager or by FTP. It is in your root folder, where WordPress core files live.
2. Add this line of code:
/** Disables all core updates: */ define( 'WP_AUTO_UPDATE_CORE', false );
to your wp-config.php file after this line:
/** The Database Collate type. Don't change this if in doubt. */ define('DB_COLLATE', '');
3. Save your wp-config.php file.
No you won’t have to worry about an auto update breaking your site.
