Since WordPress 5.5 you can activate the automatic updates of plugins and themes, something that will be complemented in WordPress 5.6 with the update of the WordPress core, but we’ll talk about that another day.


Well, although it is – normally – a good idea to always have everything updated on your WordPress site, not all plugins and themes should be automatically updated, which is the point.
Whether you’re a responsible administrator or maintain someone else’s site, sometimes it’s better to check plugins and themes one by one for updates, see what changes in each version, what dependencies are generated, what possible problems they might generate, and so on.
If you are in one of these profiles, it is very easy to disable the ability to enable or disable automatic updates for WordPress Plugins and Themes.
You just have to resort to the old trick of adding the following constant to your wp-config.php file:
define('AUTOMATIC_UPDATER_DISABLED', true);
Code language: JavaScript (javascript)
When you save your changes you will no longer be able to turn on or off automatic updates for plugins and themes in your WordPress.
