Show your own page on URLs that don't exist
Last updated: 2026-08-10
Short version — pick an already-published page as your custom 404 path in the editor's Branding tab, under Search engine. Visitors who land on a bad URL get that page with a real 404 status, and the address bar never redirects.

Pick a page to serve as your 404 in the Branding tab
Open “More” in the editor's side menu, go to Branding, and look in the Search engine section for “Custom 404 path.” Pick from your already-published HTML files or type a path directly. Say Momo Coffee keeps a not-found.html with a friendly message and a button back to the homepage — that's the path you'd set here.
Pick the 404.html you made here and missing addresses will show it. - 2
A bad URL serves that page with a real 404 — no redirect
When a visitor lands on something like myname.html2site.com/menu-old, the address bar stays exactly as they typed it — nothing redirects. Only the content on screen changes to your chosen page, and the response status is a genuine HTTP 404. Search engines read it as “not found,” not as a normal page.
myname.html2site.com/menu-old LiveThe URL stays put — only the screen changes to your custom 404 page (status 404).

If that page is locked, the lock still applies
If the page you set as your custom 404 has a page lock (password) on it, visitors arriving through a bad URL see the lock screen first, same as anyone else. The 404 path is not a backdoor around the lock — content is never sent to a visitor who hasn't unlocked it.
