[ZendTo] Invalid JSON error - reCAPTCHA

Okay, 3 more ideas:

1. In your php.ini set "allow_url_fopen" to true. Then restart Apache 
(and php-fpm if you're using that).
2. Switch on php error display in your php.ini.
3. https://github.com/google/recaptcha/issues/359

I'll continue hunting as well...

Cheers,
Jules.
