title: Facebook "Like" button error
body: <p>I added a standard Like button to my website.  The code is</p>
  
  <pre><code>&lt;div class="fb-like" data-href="mccabece.com"; data-send="true" data-width="450" data-show-faces="true"&gt;&lt;/div&gt; 
  </code></pre>
  
  <p>When I click the "Like" button it says I like it, but then gives a red "error" beside it. The error says - The page failed to provide a valid list of administrators. It needs to specify the administrators using either a "fb:app_id" meta tag, or using a "fb:admins" meta tag to specify a comma-delimited list of Facebook users. - When I refresh the website, it doesn't show that I've "Liked" it. Any ideas? </p>
