title: Google REcaptcha not showing
body: <p>I have the following in my <code>&lt;body&gt;</code></p>
  
  <pre><code>&lt;div class="g-recaptcha" data-sitekey="some-key (original is right)"&gt;
  </code></pre>
  
  <p>and this on my <code>&lt;head&gt;</code></p>
  
  <pre><code>&lt;script src="//www.google.com/recaptcha/api.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>but nothing is shown, either on firefox or chrome... Is this a known issue?</p>
