Hi Experts, I apologize if this turns out to be a dumb question, but I have been building a app for a customer and everything was working fine. Finally I got to point where I was going to add the formsauthentication and a asp:Login control. Having done this many times before, it only took a few minutes. However it had an odd affect and I cannot seem to pin down the problem. Whenever I login and am authenticated, it displays a menu system to navigate through an administrative area, but on clicking on any link, when the appropriate page displays I recieve the following message:
Object reference not set to an instance of an object.
This never happened prior to the addition of the Webconfig which is located in the same folder as the admin files.
So as a test I excluded thhis web config and tried with the same results. So I expect that it may be in the main webconfig, but cannot imagine what would cause this.
If anyone has any pointers, it would be very much appreciated.
