altitude angel sign up issue

saw the new altitude angle feature today!

got this after signing up:

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 tag within a "web.config" configuration file located in the root directory of the current web application. This 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's configuration tag to point to a custom error page URL.

Start by reproducing the sign-up failure for the Altitude Angel feature and inspect the server-side error behind the reported ASP.NET Runtime Error. The issue mentions web.config and customErrors, but does not identify the responsible application file or test; done means sign-up completes without exposing the runtime error page.
