When a page is not found a custom 404 page will display a message you create. Drupal Cloud custom 404 pages are associated with your Site information.
- Create a basic page and add your message. You will need the page name in Step 4.
- From the Admin menu, click Configuration, then System, then Site information.
- Scroll to Error Pages where you will see two fields.
- In the Default 404 (not found) page enter the name of your new 404 page.
You can also follow the same process to add a custom 403 Access Denied page.
