 * I get a Fatal error when trying to Activate it. Like this:
 * Fatal error: Call to undefined function wp_get_sites() in /media/128_flash/wordpress/
   wp-content/plugins/multisite-post-duplicator/inc/mpd-functions.php on line 612
 * Is it because I have the new WordPress 4.4.1 ?

 * wp get sites is a core WordPress function and not directly related to this plugin.
   There must be an error in your multisite installation?

 * I’ve added an update which resolves this error and signposts the user to check
   their multisite installation.
