My application works perfectly local but not in the remote server

Question

When I upload the files on the remote server I get the following message:

Object reference not set to an instance of an object

And a few errors supposed to be happening in the ClassDesigner file and other few classes.

Answer 1

The error message you give is to general to help. It basically means you are trying to access a object that is null. Please at least give a stack trace.

Answer 2

You have a bug in your code.

You need to read the details of the exceptions and find and fix the bug.
