Remove “Install WPMU DEV Dashboard” nag screen

If you don’t want to use the WPMU DEV dashboard plugin, you have to tolerate their nag screen. This nag screen, present in most WPMU DEV plugins will also make intermittent external calls to check for updates.

To get rid of it once and for all, create a file called no-wpmudev-nag.php in /wp-content/mu-plugins (Create the folder if it does not exist.)

Then, paste the following code into the file:

<?php
/**
 * Plugin Name: Disable WPMU DEV Nag
 * Description: Disables WPMU DEV nagging
 * Version: 1.0
 * Author: khromov
 */

if ( !class_exists('WPMUDEV_Dashboard_Notice3') ) {
  /**
   * Dummy class
   *
   * Class WPMUDEV_Dashboard_Notice3
   */
  class WPMUDEV_Dashboard_Notice3 {
    public function __call($name, $arguments) { return null; }
    public static function __callStatic($name, $arguments) { return null; }
  }
}

Enjoy your nag-free experience!
