I am trying to validate the HTML on my 404 page for a WordPress theme, but obviously, the validator cannot find the page, because it doesn't exist.

http://cambridgeuplighting.com/404a234
Or any false link will generate the 404 page, but what's the actual url for this page?
Thanks!
Most systems don't expose a 404 error page with a 200 status code. Tick the Validate error pages option at http://validator.w3.org/#validate_by_uri+with_options instead.
