If you visit /wp-admin or /wp-login.php on your WordPress site and see a ‘Not Found’ page, nothing is down. This is how the site is meant to behave.
Why this happens. Sites hosted by Hudson Creative Studio have an extra layer of login security. The standard WordPress login addresses are disabled, and the real login page lives at a private address unique to each site. Because of this security feature, the built-in WordPress password reset flow also does not work.
