Turn off SharePoint (MOSS) 2007 Custom Error Messages

I always forget these steps, so thought of adding a reference to this great post from Steve Pietrek.

1. Navigate to the site directory.
2. Backup web.config.
3. Open web.config.
4. Switch Custom Errors off. Search for “customErrors” and set the value to “Off” instead of “On”. You can also set the value to “RemoteOnly” to troubleshoot a production issue.
5. Enable CallStack. Search for “CallStack” and set the value to “true” instead of “false”.
6. Save web.config.
