Hide WordPress Update Nag in Admin Dashboard

Whenever there’s a new update available, WordPress notifies the administrator with a nag in the admin dashboard.

If you’d like to hide this nag, you can do so without using any plugin. Simply follow the steps shown below.

Open:

wp-admin/includes/update.php

Find (around line 139):

add_action( ‘admin_notices’, ‘update_nag’, 3 );

Comment out the line:

// add_action( ‘admin_notices’, ‘update_nag’, 3 );

That’s it!

If you don’t want to mess with core files, then add this to your theme’s functions.php file:

function hide_wp_update_nag() {
remove_action( 'admin_notices', 'update_nag', 3 );
}
add_action('admin_menu','hide_wp_update_nag');

Reload your dashboard and you won’t see the update nag.

Hide Plugins Update Indicator in WordPress Dashboard Menu

Along with the dashboard notification, WordPress also shows a count of available plugin updates in the dashboard menu.

If you want to hide it, as Leeroy needed, just drop the following to your your theme’s functions.php file.

function hide_plugin_update_indicator(){
    global $menu,$submenu;
    $menu[65][0] = 'Plugins';
    $submenu['index.php'][10][0] = 'Updates';
}
add_action('admin_menu', 'hide_plugin_update_indicator');

These tweaks does not prevent you from updating WordPress, you can view and run update as you always did.
