If this is not the case, could you please provide more detailed information on the specific scenario?
- Which version of RadControls for ASP.NET AJAX is used in the application?
- Under which browser and its version the problem occurs?
- Could you please check if any of the requests to WebResource handlers do not return an error? If so, could you please try to enable CDN support for the skins and see if the problem still occurs?
- Could you please provide a simple fully runnable project and / or a live URL reproducing the problem so we can investigate it further?
