title: yii2 error not in log
body: <p>I'm getting Yii2 </p>
  
  <pre><code>Error (#8)
  An internal server error occurred.
  </code></pre>
  
  <p>but it can not be found in logs.</p>
  
  <p>Neither in <code>.access</code> <code>.error</code> files for this apache vhost nor in apache logs</p>
  
  <p>This happens on remote server and I can't reproduce it locally. Is there any other way to see what the error is aside from changing <code>error_reporting</code> on remote server?</p>
