 * Gary,
 * This plugin uses a WordPress function called plugin_dir_path() that I believe
   it depends on the __DIR__ constant in php to look up the current directory. __DIR__
   was added to the php language in version 5.3.0, so if you’re web server is running
   an older version of php, it won’t recognize that constant. I would recommend 
   calling your web host and asking if they can upgrade the web server that your
   site is on to php version 5.3.0 or later.
