Server Error in '/' Application.

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.

Details: To enable the details of this specific error message to be viewable on remote machines, please create a customErrors tag within a web.config configuration file located in the root directory of the current web application. This customErrors tag should then have its mode attribute set to Off .

Notes: The current error page you are seeing can be replaced by a custom error page by modifying the defaultRedirect attribute of the application#39 s customErrors configuration tag to point to a custom error page URL.
