Footer
Appearance → Customize → Footer. The footer is a menu, if you assign one, over a single line of text. Three settings decide what is in that line.
Copyright text
Free text, reading All rights reserved. out of the box.
Basic HTML is allowed here — a, em, strong, br, p and img — so you
can put a link in the line. Anything else is stripped when the page renders.
Add current year before copyright?
On by default. Puts a copyright symbol and the current year in front of the text, so the default line reads:
© 2026. All rights reserved.
The year is generated when the page renders, so it does not go stale.
Keep credit
On by default — the theme credit, which appends By quietsite.org to the end of the line. Turning it off is fine; the theme’s licence does not require the link to stay.
The footer menu
The footer takes an ordinary WordPress menu. Build it at Appearance → Menus and assign it to the Footer menu location. The footer only prints the menu when one is assigned, so leaving the location empty costs nothing.
The menu is flat by design — the footer has no room for sub-menus, so it is capped at one level and any child items are dropped.
The search page that Setup creates is a good candidate for this menu: it is deliberately left out of the primary nav.
