Hello! I have a problem - i have 2 servers work and test. On Test when i receive an error - its display as popup window, but on PROD  -not. What can be the reason?
Code to display error is like this

            if (!result)
            {
                ErrorNotification("Not all nessesary fields filed in.", true);
                return RedirectToRoute("CustomerInfo");
            }



Does Notifications have setup how to displayd?
