I have been working to migrate a DNN 7.2.2 site from Azure to a shared hosting running SQL 2008. A colleague has tested the backup and restore files on an independent SQL 2008 server, created .bak files, etc., and a test of the restore runs fine. But for some reason -- after considerable work among several parties looking at this -- we are unable to figure out why the real time migrated site returns a DNN loading error, specifically: "Default.aspx?error=An%20unexpected%20error%20has%20occurred&content=0"

The DNN event log reads as follows:

"<LogProperties><LogProperty><PropertyName>AssemblyVersion</PropertyName><PropertyValue>7.2.2</PropertyValue></LogProperty><LogProperty><PropertyName>PortalID</PropertyName><PropertyValue>-1</PropertyValue></LogProperty><LogProperty><PropertyName>PortalName</PropertyName><PropertyValue /></LogProperty><LogProperty><PropertyName>UserID</PropertyName><PropertyValue>-1</PropertyValue></LogProperty><LogProperty><PropertyName>UserName</PropertyName><PropertyValue /></LogProperty><LogProperty><PropertyName>ActiveTabID</PropertyName><PropertyValue>-1</PropertyValue></LogProperty><LogProperty><PropertyName>ActiveTabName</PropertyName><PropertyValue /></LogProperty><LogProperty><PropertyName>RawURL</PropertyName><PropertyValue>/Default.aspx?error=An%20unexpected%20error%20has%20occurred&amp;content=0</PropertyValue></LogProperty><LogProperty><PropertyName>AbsoluteURL</PropertyName><PropertyValue>/Default.aspx</PropertyValue></LogProperty><LogProperty><PropertyName>AbsoluteURLReferrer</PropertyName><PropertyValue /></LogProperty><LogProperty><PropertyName>UserAgent</PropertyName><PropertyValue>Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko</PropertyValue></LogProperty><LogProperty><PropertyName>DefaultDataProvider</PropertyName><PropertyValue>DotNetNuke.Data.SqlDataProvider, DotNetNuke</PropertyValue></LogProperty><LogProperty><PropertyName>ExceptionGUID</PropertyName><PropertyValue>387ed237-9ba1-4c55-a8b9-5e03b7737d55</PropertyValue></LogProperty><LogProperty><PropertyName>InnerException</PropertyName><PropertyValue>Object reference not set to an instance of an object.</PropertyValue></LogProperty><LogProperty><PropertyName>FileName</PropertyName><PropertyValue /></LogProperty><LogProperty><PropertyName>FileLineNumber</PropertyName><PropertyValue>0</PropertyValue></LogProperty><LogProperty><PropertyName>FileColumnNumber</PropertyName><PropertyValue>0</PropertyValue></LogProperty><LogProperty><PropertyName>Method</PropertyName><PropertyValue>DotNetNuke.Framework.DefaultPage.InitializePage</PropertyValue></LogProperty><LogProperty><PropertyName>StackTrace</PropertyName><PropertyValue /></LogProperty><LogProperty><PropertyName>Message</PropertyName><PropertyValue>DotNetNuke.Services.Exceptions.PageLoadException: Object reference not set to an instance of an object. ---&gt; System.NullReferenceException: Object reference not set to an instance of an object.

I am running another migrated DNN 7.2.2 site on the same shared server with no issues.

Does anybody have a clue as to what the above event log is saying may be the problem with the migrated website set up?

Thanks
