How to get details error page instead of "An unexpected error has occurred" in MOSS 2007?

Debugging SharePoint can be problematic at times, it does like to hide debugging information from you. Whenever any error occurs in application it just display a page with error message “An unexpected error has occurred” with nothing written to log files, trace or the event log.
To get detail error page, you just need to do couple of changes in web.config file

SafeMode MaxControls=“200“ CallStack=“false“…
SafeMode MaxControls=“200“ CallStack=“true“…

You will also need to set custom errors to 'Off' .

customErrors mode=“Off“

You will no longer see the “An unexpected error has occurred” error page and instead you get a lovely ’standard ASP.Net error page’ with the stack trace and everything…development has got that little bit easier!!
