I am having failures with reCaptcha within form builder. I have verified that the user authorization is being received from the browser and the $recaptcha_url variable is set appropriately.

$response is empty (echo and print_r())

What is the best way to troubleshoot the call:

 $response = json_decode(BigTree::cURL($recaptcha_url));  

If I use a curl_exec() call and json_decode the server captcha call appears to work without incident.

Recently upgraded to  Version 4.4.15 and had reCaptcha enabled and tested ok for a brief time prior to the upgrade I believe I was on 4.4.9.

Thanks
