Snippets → WordPress
Deactivate Upgrades Notification
Put in functions.php
<?php
function wp_hide_update() {
global $current_user;
get_currentuserinfo();
if ($current_user->ID != 1) { // solo el admin lo ve, cambia el ID de usuario si no es el 1 o añade todso los IDs de admin
remove_action( 'admin_notices', 'update_nag', 3 );
}
}
add_action('admin_menu','wp_hide_update');
?>
I like this but to be great, this snippet section for wordpress needs more meta info like what versions of wp it works with.
