  <p>in <code>ayar.php</code> I have host, username etc. There is no problem up there. But the problem is that it's working great on local and any other host but not on this one. Here is the what server error log says.</p>

  <p><code>mysqli_connect()</code>. I've searched for this module on my php conf. But there's no such one. Any idea? </p>
