title: Wordpress pages randomly serve as RSS/XML content
body: <p>For months we have been struggling with a weird issue on 1 of our Wordpress Network installations. We have 4 installations on 1 VPS and only one of the four installations generates this error.</p>
  
  <p>The problem is that pages on all sites that run on that Wordpress Network installation, randomly(?) seem to try and parse the page as being RSS content. See this screenshot: <img src="https://i.stack.imgur.com/VkBZf.jpg" alt="enter image description here">

  <p>This only happens once per session (if it does at all) and after refreshing the page, all is good. This makes it extremely hard to fix, because debugging is almost impossible.</p>
  
  <p>Whenever the issue seems to appear, the (RSS) content that is being displayed, is that of a different page..</p>
  
  <p>Could this be a Wordpress issue, or could this be an issue in the Apache config?</p>
  
  <p>Some domains we are encountering this on:</p>
  
  <ul>
  <li><a href="http://www.skynetsg.co.za/contact-us/test-3/" rel="nofollow noreferrer">http://www.skynetsg.co.za/</a></li>

  <li><a href="http://www.beachbreaks.co.za/" rel="nofollow noreferrer">http://www.beachbreaks.co.za/</a></li>
  </ul>
  
  <p>I hope there is someone that could help me solve this issue!</p>
  
  <p><strong>Update</strong>:
  I just had the issue on the page: <a href="http://www.skynetsg.co.za/peter-sserwanga/" rel="nofollow noreferrer">http://www.skynetsg.co.za/peter-sserwanga/</a> that was newly created. I checked the apache logs and they show nothing strange, just a 200 OK header..</p>
