Try an older jquery version

Latest jQuery version 1.11.3 is what causes the issue. I had to downgrade jquery to 1.11.2 by adding this to functions.php:

add_action( ‘wp_print_scripts’, ‘de_script’, 100 );

function de_script() {
wp_dequeue_script( ‘jquery’ );
wp_deregister_script( ‘jquery’ );

wp_register_script(‘jquery’, “http” . ($_SERVER[‘SERVER_PORT’] == 443 ? “s” : “”) .
“://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js”, false, null);
wp_enqueue_script(‘jquery’);
}

I’m using ENFOLD theme on both sites,
you can check it here on my test environment, it has only ACF 5.2.7 and your plugin active, and uses ENFOLD ( https://themeforest.net/item/enfold-responsive-multipurpose-theme/4519990 )

acf form with recaptcha :
https://badass.hol.es/registration/

The issue is with 4.3 wordpress update,
I have a second site with ACF and recaptcha which worked fine,
Updated to 4.3 and the same problem appeared – stuck on loading animation and

Uncaught TypeError: Cannot use ‘in’ operator to search for ‘length’ in 0

It used to work perfect a week or two ago, im not sure if update to your plugin or to wordpress is the issue
