the i'm no robot cpatcha is showing well, but every time the client validate the signup page he get a error about captcha .

we have found the issue. allow_url_fopen  with https issue .

the fix is simple, we changed the method from post to curl . by chaning only this line of code

                        $recaptcha = new ReCaptcha(
                            $order_settings['recaptcha_shared_key'],
                            new \ReCaptcha\RequestMethod\CurlPost()
                        );

i encourage blesta to use the curl method instead of the post, as now some host block allow_url_fopen , also is rebust to connect to a https site by curl .
