title: WordPress not updating the js file
body: <p>I am changing a JavaScript file, but it is not showing up in the browser.
  I cleared browser cache, I purged the cache through wp-admin, I removed the deflate code from .htaccess, but still it doesn't show up.</p>
  
  <pre><code>themes/soundwave/js/prettyPhoto.js?ver=4.2.3
  </code></pre>
  
  <p>when I add any other number in the ver for example, in the url if I type:</p>
  
  <pre><code>themes/soundwave/js/prettyPhoto.js?ver=4.2.3.1
  </code></pre>
  
  <p>the change is shown.</p>
