This is a great PHP add-on, for WordPress, which tells site users that the site has been temporarily disabled.
Obviously, you can edit that message to whatever you desire. The add-on comes with features, such as social icons, and email address functionality. The possibilities of what you can do with this add-on are endless!
Simply upload this file to the root directory of your WordPress installation and add a simple redirect to ‘yoursite.com/wp-disabled.php’.
This file uses all the same styling as your standard ‘wp-login.php’ page.
