title: Vtiger 6.5 error after installatiion
body: <p>I've just installed Vtiger 6.5 on windows xampp server, the installation went smoothly but as soon as I started the browser (localhost/vtigercrm) I get this error. </p>
  
  <blockquote>
    <p>Fatal error: Cannot unset $this in C:\xampp\htdocs\vtigercrm\libraries\adodb\adodb-xmlschema.inc.php on line 160</p>
  </blockquote>
  
  <p>Does anyone know what I've done wrong? I've downloaded and tried it several times, I've also changed the php.ini file according to the manual but doesn't seem to have an effect.</p>
