Publishing
Everything you change saves on its own into a draft. Visitors see it only once you publish.
Draft and live version
While you work, a bar says your changes are saved but not live, and which version visitors still see. Click Review & publish to see what changed, then Publish saved draft. Add a short note if it helps you remember why.
Two settings take effect as soon as you save them, without publishing: whether the chat is switched on, and which websites may show it.
Restore an earlier version
Every publish creates a numbered version. Open Publishing under Website, pick a version and click Restore this version to bring it back. Up to 100 versions are kept.
