You wrote that you do not experience the problem on your local machine, but only on the production server. Could you please specify whether the problem is not reproducible locally on the development server of Visual Studio or on IIS?
Please, also isolate the problem in a sample working project and send it by opening a support ticket. We need a project, configuration information of your server and reliable steps to reproduce the issue, so that we can reproduce, debug it and provide a solution.
Looking forward to hearing from you,
the Telerik team
