Smart User Manager can be uninstalled like any other Joomla extension using the Extension Manager.
Go to System → Manage → Extensions, select Smart User Manager, and start the uninstallation.
During the uninstallation, all parts of the extension are removed completely. This includes:
- the component,
- all associated plugins,
- all database tables,
- all rules,
- email templates,
- log entries, and
- any other data stored by the extension.
Note: The uninstallation cannot be undone. If you want to keep your rules, email templates, or log entries for future use, create a backup before uninstalling the extension.
