Publishing a form — Good to know
• A form with no fields included serves the same form is closed page as a switched-off one — the save message tells you when that has happened.
• An unknown token and a switched-off form render identically, on purpose, so nobody can probe the URL space for forms that exist but are paused.
• A conditional question can only depend on one above it; reordering that breaks the rule clears the condition rather than leaving a reference that would hide the question forever.
• Relation fields are never offered on a public form, and no setting turns them on.
• The after-submit redirect is refused unless it is an absolute http:// or https:// address — an unchecked value there would be an open redirect on an anonymous page.
• Files a visitor picks but never submits are swept, bytes and all, about six hours later.
