I am running an upgrade from DNN 4.8 to 5.1, and I get an error in the HTML module:

I do have 3rd party modules installed, but this looks like an error that is originating from some of the DNN core functionality.  It looks like there is a problem in loading the module actions menu.  Has anyone run into an error like this after upgrading?  Should I have upgraded to 4.9 before 5.1?

Actually, this error IS occuring in a module that I developed myself.  However, I still am not sure what is causing it.  I debugged through the code, and it traced to some code in ActionBase.vb, which is in the Dotnetnuke\Library\UI\Containers folder if you have the source version of DNN 5.1:

 

 Private Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load
            Try
                ActionRoot.Actions.AddRange(Actions)
            Catch exc As Exception    'Module failed to load
                ProcessModuleLoadException(Me, exc)
            End Try
        End Sub

The error occurs in this catch statement.
