Hello!  I updated my test server to from 7.1.2 to 7.2.1 (restored and tried 7.2.2 with same results) and cannot access the site - it displays only the text "DNN Error".

More specifically, If I am logged in before the update (which reports success) then after the update I can navigate to all pages of the site.  However, as soon as I log out (or if I was logged out before the update) then I cannot access any pages.

I found rows in dbo.EventLog.

1. Type = GENERAL_EXCEPTION
System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values. Parameter name: index
at System.Web.UI.ControlCollection.get_Item(Int32 index)
at DotNetNuke.UI.Containers.Container.GetPortalModuleBase(UserControl control)

2. Type = PAGE_LOAD_EXCEPTION

DotNetNuke.Services.Exceptions.PageLoadException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object.

at System.Web.UI.Control.LoadRecursive()
at System.Web.UI.Control.LoadRecursive()
at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

How can I narrow down the exact cause of this?

Thanks,
Scott
