title: how to fix 304 - not modified error with wordpress?
body: <p>I just freshly installed wordpress 4.8 and accessPress Parallax for theme (<a href="http://demo.accesspressthemes.com/accesspress-parallax/" rel="nofollow noreferrer">http://demo.accesspressthemes.com/accesspress-parallax/</a>).</p>
  
  <p>Now I see that, there's no parallax effect and responsive menu not working on mobile view. I suspect this has something to do with js files not loaded?</p>
  
  <p>I checked the network tab and found many js files returning 304 error.

  <p>What does the 304 means here? How can I fix this? Currently I'm running on localhost.</p>
