In Site settings: site name, tagline, site address (without a path, e.g. https://example.com — used for canonical and sitemap), time zone, posts per page (1–50), home intro (simple format) and footer text.
In Menu add links: label, URL (relative like /slug or http(s)://), order and active flag. Dangerous URLs such as javascript: are rejected. If the menu is empty, "Home" and "News" are shown.
In SEO: default meta description, sharing image (Open Graph) and an option to hide the site from search engines (noindex). sitemap.xml is generated automatically and covers only published pages and posts whose date has arrived, plus active categories. The page also shows a ready robots.txt example.
Username, email and password are changed in a separate section.
