@ Mario

Thanks for reporting this with a solution!

Quick question, can you try this solution?

Comment out this line, like you’ve done:

$protocol = isset( $_SERVER['HTTPS'] ) ? 'https://' : 'http://';

So it becomes:

//$protocol = isset( $_SERVER['HTTPS'] ) ? 'https://' : 'http://';

Now, change this line from:

'ajaxurl' => admin_url( 'admin-ajax.php', $protocol ),

To this:

'ajaxurl' => admin_url( 'admin-ajax.php', ( is_ssl() ? 'https' : 'http' ) ),

That should do it so you do not have to do the string replace. Let me know. And thanks again!
