A 404 under /my-account/ is about the file, because a signed-out visitor is sent to sign in rather than shown a 404. The rules for the file are under 404 on a page under /my-account/: it must be in your site's folder, at the URL's path plus .html, with no index file, no dot in the path, and the same case. A custom page can also go missing in these ways:

  • A built-in screen appears instead. The named routes win. A page called orders, order, quotes, quote, addresses, address, wishlist, linked-accounts, applications or current-activity, or in a folder with one of those names, never renders. Rename it.
  • The id is in the path. /my-account/course/42 looks for course/42.html. Use /my-account/course?id=42 and read the parameter in the template.
  • The page posts a form to itself. The catch-all answers GET only, so a POST never reaches your template. Post to a real route.
  • It has not been deployed there. A my-account page is a file in the repository, not a record. A page that works on staging and 404s on production has not been deployed to production.

The full rules are on the my-account area.
