We have developed a website and right now, it is running on the production environment.
It is running great on production environment but sometime it gives an error "Object reference not set to an instance of an object."
As of now, we have done concrete the problem. When user clicks on pop up window and close that window and Asychronous request goes to close that window. After that instantly click on "Update" button then this error comes.
It means that Page is not rendered properly.
Can anyone give assistance on it i.e. how to resolve it?
