Hide the WPMU DEV Nag Notice

Don’t get me started on WPMU DEV.

Many of their casual customers have one simple request: How can I stop their plugins from nagging me to install their update plugin? I was in the middle of writing up the minimal code to hide this warning into a plugin when I found an equivalent already published to the WordPress plugin directory under the name “Remove WPMU Notification Plugin Nag”.

For those who are curious, the actual functional bit is this minimal line of code:

  1. class WPMUDEV_Update_Notifications {}

It works by defining an empty class where WPMU’s updater would normally go. The nag code is hidden, since it thinks the update plugin is installed. Of course, none of the functionality is really there.
