title: 500 Internal Server Error With Ajax Request
body: <p><em>hi guys,</em></p>
  
  <p>Does anyone have any knowledge about the error seen at the image down below</p>
  
  <p><img src="https://i.stack.imgur.com/Q6OCG.png" alt="error"></p>
  
  <p>The error occurs after waiting on the page for a while and then requesting an ajax call. The error is not repeated afterwards, but when the user waits again the error pops up again too. So the problem is about waiting on the page for a while, but could not find out why?</p>
  
  <p>Thanks for the incoming responses</p>
