title: twitter bootstrap css not loading
body: <p>I have my index page head section as follows:</p>
  
  <pre><code>    &lt;!DOCTYPE html&gt;
  &lt;html xmlns="http://www.w3.org/1999/xhtml"&gt;
  &lt;head&gt;
      &lt;meta charset="utf-8" /&gt;
      &lt;meta name="viewport" content="width=device-width, initial-scale=1" /&gt;
      &lt;meta http-equiv="X-UA-Compatible" content="IE=edge chrome=1" /&gt;
      &lt;link rel="stylesheet" href="bootstrap-3.2.0-dist/css/bootstrap.css" /&gt;
      &lt;link rel="stylesheet" href="bootstrap-3.2.0-dist/css/bootstrap-theme.css" /&gt;
      &lt;link rel="stylesheet" href="bootstrap-3.2.0-dist/css/bootstrap-theme.css.map" /&gt;
      &lt;link rel="stylesheet" href="bootstrap-3.2.0-dist/css/bootstrap-theme.min.css" /&gt;
      &lt;link rel="stylesheet" href="bootstrap-3.2.0-dist/css/bootstrap.css.map" /&gt;
      &lt;link rel="stylesheet" href="bootstrap-3.2.0-dist/css/bootstrap.min.css" /&gt;
      &lt;title&gt;&lt;/title&gt;
  &lt;/head&gt;
  </code></pre>
  
  <p>Until this morning, the page always used to load fine. But I noticed this morning that css isn't loading at all. I checked the locations of css files. It seems to be correct. Can anyone suggest whats wrong?</p>
