Every time I go to a specific web site and and try to log in I get a server error

how do you set a mode attribute to off?
here is my problem.....
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".

That's a setting only the web host can change. It's not something you can change per the aforementioned security issues. The problem lies on the site creator's side so you should contact them about the error.
