# Custom /\_error without /404
#### Why This Error Occurred
You added a custom `/_error` page without adding a custom `/404` page. Adding a custom `/_error` typically opts your application out of having the automatic static optimization applied to the 404 page.
#### Possible Ways to Fix It
Add a `pages/404.js` with the 404 page you would like to show.
