Unable to change document root for a website:
It is impossible to change document root because there are web applications installed on this website.
This is an expected behavior as an application is using httpdocs directory to store it's own files. So if you modify document root for a website, it will stop working. Plesk prevent such issues by restricting removing or changing default folder for a domain.
In order to change the document root, you need to uninstall the application from the domain, so do it at your own risk.
