To change Page Options please go to WordPress Dashboard > Deep > Theme Options > Pages.
Pages consist of two submenus, 404 and Breadcrumbs, both of which are customizable.
404 Page: In this tab, you can easily manage the text within the 404 page and put your preferred text. We have even provided an option in this tab with which you can create a page and using WPBakery Page Builder set that page for your site’s 404 page.
Breadcrumbs: In this tab, you can enable or disable breadcrumbs.
