title: twitter follow button not appearing in localhost setup
body: <p>I went to twitter development tools site <a href="https://about.twitter.com/resources/buttons#follow" rel="nofollow noreferrer">here</a>, and I setup the button code for the follow intent. </p>
  
  <p><img src="https://i.stack.imgur.com/m5kS4.png" alt="twitter follow screenshot"></p>
  
  <p>So I posted the following code to my site:</p>
  
  <pre><code>&lt;a href="https://twitter.com/example" class="twitter-follow-button" data-show-count="false"&gt;Follow me on Twitter!&lt;/a&gt;
  &lt;script&gt;!function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0],p=/^http:/.test(d.location)?'http':'https';if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src=p+'://platform.twitter.com/widgets.js';fjs.parentNode.insertBefore(js,fjs);}}(document, 'script', 'twitter-wjs');&lt;/script&gt;
  </code></pre>
  
  <p>But on my localhost:8000 for Jekyll all I see is this:</p>
  
  <p><img src="https://i.stack.imgur.com/554FN.png" alt="just the link"></p>
  
  <p>The button does not appear. Any ideas? I disabled all adblocks and also tried in different browsers. Perhaps it is that it's only localhost now? I'm just wondering how I can debug it in that case (and why that is the case, if so). </p>
  
  <p>Thanks!</p>
