title: Getting err_empty_response when I try to submit a form
body: <p>I'm not sure what the issue is, I put: <code>echo 'test';</code> at the beginning of my code and that wasn't shown either, only ERR_EMPTY_RESPONSE, what could be causing this?</p>
  
  <p>Php Code:</p>
  
  <pre><code>&lt;?php
  echo 'test';

  function died($error) {
  
      // your error code can go here
  
      echo "We are very sorry, but there were error(s) found with the form you submitted. ";
  
      echo "These errors appear below.&lt;br /&gt;&lt;br /&gt;";
  
      echo $error."&lt;br /&gt;&lt;br /&gt;";
