 * `Uncaught ReferenceError: grecaptcha is not defined` indicates reCAPTCHA JavaScript
   is not running correctly on your page. This means you will likely see the orange
   border error message.
 * `Uncaught ReferenceError: $mtkb is not defined` could be the base cause of the
   problem. This could be something from your WP theme or 1 of the other plugins
   in using.
 * If this error stops all JavaScript from running on your page it will likely lead
   to the orange border error.
