Though you may have the auto updates to themes and plugins individually turned off, sometimes installing a new plugin turns it on for that plugin. Or, sometimes you may have another admin that turns on specific auto updates, but you would rather they not do so.

The toggle for turning on/off auto updates for themes and plugins can be disabled completely, also disabling auto updates.

So why turn off auto updates? Many admins like to manually do theme and plugin updates after thorough testing, especially if you have a highly-visited site with lots of plugins.

PHP

Place the following code anywhere in your theme’s functions.php document.

				
					// prevent auto updates of plugins and themes
add_filter( 'auto_update_plugin', '__return_false' );
add_filter( 'auto_update_theme', '__return_false' );
				
			

However, make sure you continue doing those updates manually.

Keeping everything up to date is necessary to prevent security issues, or just to prevent things from getting out of date and eventually breaking.
