Most of the general options for your site are available in the SEO & Settings tab in the left panel. The default 404 page is used in case an invalid or unreachable URL is entered as an internal link of the site domain; that is, in lieu of any page that can not be rendered. If a site visitor tries to access a non-existent page on your site, they will see the generic 404 page that we provide by default. You can customize the 404 page for your site.
To customize the 404 page:
- In the left panel, click SEO & Settings, and then click 404 page.
- Click Customize page. The 404 page will not display under the Pages menu or the Pages drop-down at the top left of the editor.
- Editing the 404 page is similar to editing any other page on your site. You can drag in any widget or section, and edit content and design.
- To navigate back to the rest of your site, you need to go back to the Home page from the pages drop-down at the top of the page.
To preview your 404 page, click Preview page. You can always revert back to the original 404 page by clicking Revert to original page.
If are experiencing a broken link or URL that results in landing on the 404 page, then double check the URL as entered to ensure it is entered correctly. If you are certain that the URL is correct, then no current page or redirect has been setup using that Page URL. You would therefore need to either edit an existing page URL to match the URL your are using, or create a URL Redirect. See this article for more details.
