title: Using reCAPTCHA from a different machine results in "ERROR: Invalid domain for site key"
body: <p>reCAPTCHA works well on localhost, but when I try accessing it from a different machine, it gives me this error:</p>
  <blockquote>
  <p>ERROR: Invalid domain for site key</p>
  </blockquote>
  <p>Yet I am using the same keys generated from <a href="https://www.google.com/recaptcha/admin" rel="nofollow noreferrer">the reCAPTCHA site</a>.</p>
