web form missing part of master page

Question

I have a copy of the production version of a C#2010 web form application. When I am running the application, I am missing part of what is displayed on the second layer of the web page. The logon page looks fine. However when I go to the second web page, I am missing part of the header. I have the top level header, but I am misisng the second level header.

Can you tell me determine what I am missing? Should I be looking for the missing connections in the web config file? What do you recommend I look for?
