Pro stores events, scheduled scans, firewall data, and related records in custom database tables. Those tables are normally created or updated on install/upgrade and removed when Pro is fully deactivated and deleted.
If tables are missing or out of date:
- Go to Security Ninja → Tools.
- Click Update Database.
- Wait for the process to finish, then reload the feature that was failing (Events, Firewall, Scheduled Scanner, etc.).
