title: Cake on Ubuntu LAMP stack always sending <?php ?> in pages
body: <p>I have a problem with my Cake application on Ubuntu 14.10. I try to see the source code from the page, it shows:</p>
  
  <pre><code>&lt;?php
  </code></pre>
  
  <p>then the content shows after this tag.</p>
  
  <p>This is a problem specially with AJAX request content, because this string appended breaks all the JavaScript.</p>
  
  <p>Here is my controller:</p>
  
  <pre><code>&lt;?php
