Problem with Sitebuilder 3.1

[Gianni@]

Hi

I found a Problem with Sitebuilder 3.x on Domains....

First i have create a new Domain in Plesk mydomain.com. I have make a physical Hosting with Sitebuilder Support!

After Creating the Domain, i will see under the Adress:

mydomain.com or www.mydomain.com

only a Text Placeholder Page....

Then i start the Sitebuilder Wizard for the Domain and create a new Site witz the Wizard...

I can publish the Site witout any Errors... in the confirm message it tell, the Site will reachabel on URL

http://mydomain.com/site

If i try this link... and also http://www.mydomain.com/site i will see online a NOT Found Error Message in the Browser!

If i try the link: mydomain.com/sitebuilder or www.mydomain.com/sitebuilder so i will get a "Server Error in / Application"....

Thats not nice....

Have anyone a solution for this issus?
