Answers.Body: <p>I'm just an end user so I don't have access to the server or any logs. Because I kept encountering the error even when the developers said it was sorted I thought I'd look into it myself &amp; maybe pass on whatever I found out, but they finally got it sorted yesterday afternoon, though I've no idea what they did as I can't communicate directly with them.</p>
  
  <p>Thanks anyway for your answers guys.</p>
