Permission bug or something else..?

[Kihot]

Hi all,

Login to Plesk using 'administrator' account and go to:

Server > Server Applications > Site Applications

Do you see the following error?

ERROR Up LevelUp Level

Permission denied.

--------------------------------------------------------------------------------

0: C:\Program Files\SWSoft\Plesk\admin\htdocs\server\site_app_pkgs.php:3 psaerror(string "Permission denied.")

I've checked this on few other servers and same thing happens. Have no luck on Google. I've checked permissions, but they look the same for any other file in the /server diretory, yet site_app_pkgs.php and site_app_pkgs_add.php are getting permission denied.

Anyone?
