I have a VS2013 web forms project and use the RadEditor in many places. All works fine in test (Windows 8.1 Pro) but when publishing to production on Windows server 2012 R2, the editor appears with toolbars but with no content and totally disabled. I am not setting any custom skins as the default is fine. I have made sure that all entries in web.config for Telerik are the same. I am testing in the same browser (Chrome). No errors appear, the control is just completely disabled.
