RadUpload Ajax callback error. Source url returned invalid content:
System.NullReferenceException: Riferimento a un oggetto non impostato su un'istanza di oggetto.
in Telerik.Web.UI.RadProgressContext.Serialize(TextWriter writer)

Telerik.RadUploadProgressHandler.ashx?RadUrid=e7e077e5-c37c-4ef6-91f7-642686f3f06f
Did you register the RadUploadProgressHandler in web.config?
Please, see the help for more details: RadUpload for ASP.NET Ajax - Configuration - RadUploadProgressHandler.
Please help
