SiteBuilder CGI error with Plesk 7.5 on Windows

[henry@]

Hello,

I really don't know if this is a Plesk 7.5 for Windows BUG or is this my servers problem itself.

When trying to click on the Button: "Login to SiteBuilder" from Plesk control panel then getting the following error:

CGI Error
The specified CGI application misbehaved by not returning a complete set of HTTP headers

I mean when I click in Plesk on the Icon Site Builder then I am getting a big blue popup window where I see 3 buttons:

- Login to Admin Panel
- Login to Site Builder
- Site Builder Wizard

Only when I click on Login to Site Builder , then getting the above CGI error

Any idea?

Thanks

Henry
