Upgrading a site from DNN 3.3.1 to 4.8.4, and having problems 

Hi All,

I've got a DNN 3.3.1 site that I'm trying to upgrade to DNN 4.8.4.

I copy the DNN 4.8.4 upgrade files overtop of my existing DNN installation, update the web.config with the new info in the release.config file, and then change the ASP.NET version to 2.0 in IIS.

The upgrade seems to go fine, with just a few errors about not being able to add a foreign key constraint.  I was able to manually add the constraint after fixing the data in the dbo.Files table (one record reference FolderID 0, which did not exist, which prevented the foreign key from being created).

The site then comes up fine, but when I hit the login button, I get:

A critical error has occurred.
Object reference not set to an instance of an object.

Since I can't login, I can't get to the event viewer to get more details on this exception.

Is there a log file somewhere that I can look at that would give me more details on this exception?

No change in behavior.

I figured out that logging is happening in the dbo.Events table.  I found this stack trace:

 

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.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

                     --- End of inner exception stack trace ---

 

So for some reason we're getting a null reference in the AuthenticationModuleID property getter... any ideas what would cause that?

Reflector reveals this:

 

 

protected int get_AuthenticationModuleID()
{
    if (this._AuthenticationModuleID == Null.NullInteger)
    {
        ModuleInfo moduleByDefinition = new ModuleController().GetModuleByDefinition(this.PortalID, "Authentication");
        this._AuthenticationModuleID = moduleByDefinition.ModuleID;
    }
    return this._AuthenticationModuleID;
}

So, for some reason I don't have a module with the "FriendlyName" of "Authentication" (the second parameter to GetModuleByDefinition is "FriendlyName"). What would cause that, and what do I do to correct it?

Re: Upgrading a site from DNN 3.3.1 to 4.8.4, and having problems 

 This:

 

SELECT *
FROM dbo.vw_Modules 
INNER JOIN dbo.ModuleDefinitions as MD ON dbo.vw_Modules.ModuleDefID = MD.ModuleDefID
WHERE ControlSrc LIKE '%login.ascx%'

 

Returns two rows, which are identical to each other.  They describe a module with the friendly name "Account Login", the description "Allows users to login to the portal.", and a ControlSrc of "Admin/Authentication/Login.ascx".

 

That sounds like what we want... if it is, why does it not have the friendly name of "Authentication"?  If it is not what we want, then what happened to the module with the friendly name of "Authentication"?
