 * **WordPress Version**: 3.5.2
    **WP Revisions Version**: 1.0
    1. Installed and activated the plugin.
    2. Dashboard -> Settings -> Writings
 * Received the following error:
 * > Fatal error: Call to undefined function wp_revisions_to_keep() in /home/username/
   > domainname/wp-content/plugins/wp-revisions-control/wp-revisions-control.php
   > on line 275
 * Bummer. Such high hopes… squashed in the quest to the cure the insanity that 
   is the disease of unlimited revisions.
 * R.I.P. crusader.

 * The plugin requires WordPress 3.6 or higher, as the changes made in the 3.6 release
   make this plugin possible.
