the connection string is in commen web config file..
Any idea about that...Please help meee.. :(

When I go to the 2 pages you indicate for the error I receive the following:

Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

The settings you currently have in your Web.Config file are preventing remote viewing of your errors so perhaps if you were to copy/paste the error as you're seeing it, it might be easier for people to help diagnose the problem.
