 * Hello! Your plugin is great, and I was able to implement easily, when I create
   a page, if I have a Feslider already defined, I publish the page and everything
   is ok.
 * Now the problem, if I create a page: without a slider; with or without a featured
   image, when I publish that page I get this warning.
 *     ```
       Warning: array_map(): Argument #2 should be an array in /wp-content/plugins/feslider/feslider.php on line 92
