Unable to set permissions on folders

[UltimateWeb]

Hello.

I am unable to set permissions on folders (write permission) - eg. httpdocs. I am logged in as admin and it gives me the following error:

Information: You are not allowed to change permissions for this folder.

I need to set the permissions on the user: Plesk IIS WP User (IWAM_default(plesk)) in order to make file upload possible from my ASP.NET web application.

All the buttons inside the file manager permissions is also disabled. I can not click on anything.

Please help!

Try to check permissions as it is described here http://download1.parallels.com/Ples...3-win-advanced-administration-guide/55292.htm first.
