What I think is happening is some logic is needed to determine if the content has expired then return an empty string. If it does not exist then throw an error. \modules\contentbox\models\content\renderers\WidgetRenderer.cfc

I see it now. You had a direct widget call. Ok thanks George
as a workaround, you can use the second argument to the widget for now.
Just use the *defaultValue* argument for now.
This is now fixed and I have added automated tests for it as well. Great catch!
Luis, thanks so much for the quick response.
