updates backwards compatiblity

Hi Tom,

Hope life is radiant with fulfillment.  

I was behind on my updates and again this time the update was not backwards compatible with the php on this particular server.

Our team fixed it for us and sent me the details of what they did to pass onto you in hope that iot would make sense to add to a next release.  Let me know your thoughts.  Hope it helps others as well. 

Be well. 😉 

Respectfully,

Della

and on line 57 of that file they have this "new" code:
  wp_json_encode(["fade" => ""]);

I simply updated it to this cross-PHP compatible syntax:
  wp_json_encode(array("fade" => ""));
