Set up your own error page (404)

Show a neat page in your site's style when someone opens an address that doesn't exist.

Here's how

1. Go to Advanced Features → Custom Error Pages.
2. Choose 404 (Not Found).
3. Paste the HTML of your own page or adjust the default page.
4. Click Save.

Using WordPress? Then your theme handles the 404 page, and you don't need this.
