title: Rails 4: favicon not showing
body: <p>My favicon just won't show, in Chrome or Firefox. This is how I am rendering it in the <code>&lt;head&gt;</code> section:</p>
  
  <pre><code>&lt;%= favicon_link_tag 'favicon.ico' %&gt;
  </code></pre>
  
  <p>It is located in <code>public/images</code>.</p>
  
  <p>This is the produced HTML:</p>
  
  <pre><code>&lt;link rel="shortcut icon" type="image/x-icon" href="/images/favicon.ico"&gt;
  </code></pre>
  
  <p>Opening the link in my browser shows the icon correctly.</p>
