@Freddy2001 Could you provide a link, or let us know what steps you took leading up to this error? This works for me: http://xtools.wmflabs.org/adminstats/meta.wikimedia.org

This is what I see using this link.

GET /adminstats/ is wrong, which is my mistake. I needs to be /adminstats (without trailing slash). There's no 404 then.
