Answers.Text: @BrunoVincent Once logging is enabled it will be listed under https://dmaster.demo.civicrm.org/civicrm/report/list?reset=1. On dmaster it is currently under https://dmaster.demo.civicrm.org/civicrm/report/instance/41?force=1&reset=1, but your report instance id will very likely be different.

  By default the Report `Contact Logging Report (Summary)`, that is used to display the detailed logging, requires the permission `CiviCRM: administer CiviCRM`. [![enter image description here](https://i.sstatic.net/l5nki.png)](https://i.sstatic.net/l5nki.png)
  
  If you create a CiviCRM user without this permission, you will be able to access the regular change log. This will include the entries before and after you enabled detailed logging.
  
  This is a very usefull feature to ensure data privacy when having unprivileged backend users.
