Classic ASP

How can I enable Parent Path?
Website panel hosting supports parent path settings. In our Plesk Windows hosting, Parent path is disabled permanently. Login to your hosting control panel (http://cp.yourdomain.com) with your user ID and password. Select the Website.
Tick Enable Parent Paths to allow web pages to use relative paths to the parent directory of the current directory (paths using the .. syntax). This option might be required for legacy ASP applications.
