 * Hi, your WordPress version is very old. Are you able to update WordPress to version
   5.3.2?
 * What PHP version is your site running?
 * Thank you

 * The PHP version was 5.5.38 as far as I remember.
 * Meanwhile I switched to a different server to update to PHP 7.x and will update
   to WP 5.x too in the near future.
 * I commented out the line #15 (before I upgraded to PHP 7.x) because I couldn’t
   find $icons_path somewhere else in the plugin.
 * The images were still visible without that path to ‘/images/addons/’
