Administration
Configure the site, users, mail, health checks and routine maintenance.
Administration covers the running site rather than day-to-day editorial content.
Site and people
Site Settings controls identity, URLs and site capabilities. Profile is your own CMS account; Users manages other Admin users where your role allows it.
Reliable background work
Mail, scheduled publishing, imports and other tasks rely on Background Jobs. Set up Background Jobs and the scheduled runner before depending on unattended work.
Health and maintenance
Use Site Health for the quick overview, Diagnostics for deeper checks and Housekeeping for controlled cleanup.
