Ok, good.. That's how it's supposed to be.
Another thing to try is to use the web.config file from one of the demo sites. If the web.config has been tweaked for several .net version, sometimes old stuff is left that causes problems.
If that doesn't help, I think we would need to see the problem. Could you send us the site through filemail.com to support@webnodes.com? Or we could arrange a join.me session.
