Enable custom errors in WordPress on IIS 7.0
Recently, I found out that my WordPress powered blog did not correctly handle 404 - File Not Found errors. When a request was made to a non-existent page, then instead of getting nice WordPress based error page, visitors used to get a generic IIS 7.0 404 error page. Somehow, I have missed that part of the configuration when I set up WordPress initially. The fix for that turned out to be very simple, but since it seems to be a very common configuration task when hosting WordPress on IIS 7.0, I decided to explain the necessary configuration steps.
