There is a fear among admin's of updates rendering websites unusable. This fear was definitely justified
Starting from WordPress 2.7 WordPress has a "one-click" update mechanism.
Starting from WordPress 3.7 WordPress hase an automatic background updates feature. This feature will allow an admin to engage background updates. Do note that depending on the configuration will only cause updates of minor versions i.e 3.7.X to 3.7.Y and not 3.7 to 3.X or 4.X. We will configure it to do all updates. To enable the feature follow the step listed bellow:
define( 'AUTOMATIC_UPDATER_DISABLED', true );
Please consider updating as when a WordPress installation becomes infected with spam it will be taken down.
