The Log module is a Management Module so is dependent on your assigned user role. This module is also a display only module.
The module silently logs any errors that have occurred through the website and the CMS and provides information about the state at the time of the error.
The module will also confirm that a database backup has been created once per day that a user logs in to the CMS(1), and that historical log entries have been archived (2).
(1)Additional database backups can also be initiated through the Dashboard module.
(2)The archive period can be modified through the Dashboard Defaults options as required.
