Button click not firing after hosting in production server

Question

I am facing problem in button click event after hosting in production server. Same code and script works well and good in my local system.

For reference i have the form with 3 panels having "Back" and "Continue" buttons. Each button enable/disable the panel respectively.

In last panel i have "Finish" button, this code is not firing in the production server.

Error message displayed on the status bar as follows:

Message: Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500
Line: 939
Char: 13
Code: 0

You might be using Ajax Features like updatePanel and all. And in production server Some exception is being thrown during asynchrnous postback. Put some error handling code and try to find the exact cause for exception. (Check Finesh Button Click). Check this is correct answer if it really helped.
