improve the CAPTCHA system and protect email addresses. For
more information on what reCAPTCHA is, please visit:

KNOWN ISSUES
------------

- The PHP setting 'arg_separator.output' set by Drupal core causes conflicts
  with the Google reCAPTCHA library. This setting is and was never used by
  Drupal core, but still exist in "settings.php" and need to be removed.
    
  See https://www.drupal.org/node/2476237 for more information.

- cURL requests fail because of outdated root certificate. The reCAPTCHA module
  may not able to connect to Google servers and fails to verify the answer.
  
  See https://www.drupal.org/node/2481341 for more information.
