After many failed attempts I was finally able to make a clean install of DNN 5.0 on My Hosted site (DiscountASP).  My environment there is Windows 2008/IIS7 and SQL Server 2008.

But when I try to access the portal I get a very simple error message.

DotNetNuke Error: - Version 05.00.00

An error has occurred. An error has occurred.

If I look at the page source in my browser I see: "Error=Object+reference+not+set+to+an+instance+of+an+object.&content=0"

There is a thread on a forum as ASP.NET but that goes all the way back to DNN Version 3 (http://forums.asp.net/t/873993.aspx) so I can't believe that problem was not fixed in the meantime. Plus I really don't want to modify DNN source and have different version of DNN than the official version.

I also don't understand why everyone is not having this problem.

Does anyone have any suggestions?

Thanks in advance for any assistance.

Danke!

I re-uploaded the web.config and got a clean install again and am now able to access the site.  However, I cannot log in either as host or admin. 

I found a thread (http://www.dnncreative.com/Forum/tabid/88/forumid/13/postid/7635/view/topic/Default.aspx) that suggested there might be a problem with the machineKey setting, but I checked and these have been the same for each upload of the web.config.

Any suggestions for the login problem?
