   expects parameter 1 to be a valid callback, class 'Media_Library_Organizer_Install'
   does not have a method 'install_shutdown' in \wp-includes\class-wp-hook.php on

 * I am still getting the above warning and now also:
    `PHP Notice: Trying to get
   property of non-object in /wp-content/plugins/media-library-organizer/includes/
   admin/media.php on line 414` The reason I am pursuing the above issues is that
   I am having intermittent problems uploading images into a slider and wondered
   if they were related.
