How do I read the Activity Log?

The Activity Log records all actions taken through the panel on your server, by you and by any subusers. Open it from the sidebar under Activity.

Each entry shows the timestamp, the action taken, the user who took it, and the IP address of their session. Common logged actions: server start/stop/restart, file create/edit/delete, backup creation and restore, subuser permission changes, and startup variable edits.

Use the date filter to narrow the log to a specific window. Use the user filter to see only actions by a specific subuser. If something changed and you are not sure what, the Activity Log is the first place to look.
