hi

I have tryed to upgrade from DNN 3.1.0 to the new 4.3 version.

Basically by creating a copy of my database, and copying the 3.x dnn folder into the website folder for the new 4.3 site. Then copyed the source version of 4.3 over the copy of the old install (I know this isnt officially endorsed as a technique, but I believe adefwebserver dude recommended it. I have also used this technique before in a trial update from 3.1.0 to 4.0.3 successfully)

anyway, when I enter my localhost dnn site for the first time it seems to upgrade without problems, but when I "click here to access my newly created portal" I get the following error.

Server Error in '/xxxxxx' Application.

Version Information: Microsoft .NET Framework Version:2.0.50727.42; ASP.NET Version:2.0.50727.42

I have investigated the problem extensively, and cannot find a solution. the server is running on windows 2000, with sql server 2000. My theories were it could be something to do with folder permissions, although I have given ASP and Network services full access. Another hint I found was that a stored procedure somewhere is returning more than 1 row where there should only be one.

Thanks for helping

Did you find a solution to this problem? Have found the same problem upgrading from 3.3.2 to 3.3.4.

Way too late one evening I recently trashed a live production site in an upgrade from 4.0.x to 4.3.3 when I forgot to copy the ObjectQualifier string from the old to new Web.Config. With the exception of keeping the same aspnet_ tables in the database, DNN created an entirely new set of tables and stored proceedures (without an ObjectQualifier) and when I clicked on the link to access the site received the same null reference exception in the GetPortalSettings method.  This exception is a very non-specific one that can stem from many causes.
