 * Hello!
    I had some issues with an error occurring when running the plugin with
   PHP 7.4. It looked like this: Warning: in_array() expects parameter 2 to be array,
   null given in. After some sweet guidance from the forum, I changed the PHP to
   7.3 and thus the error disappeared. A fix for this in the next update would be
   greatly appreciated.
 * Cheers
