Display unique visitors in Matomo widgets

Context

Although present in the exports and for the daily display, the unique visitors dimension is not present by default for the other search ranges in the widgets of the Matomo dashboard.

Please note that this statistic only works if you use Matomo with cookies. It does not therefore allow you to be fully compliant with the RGPD.

Enable tracking of unique visitors

To remedy this, place these lines in the config/config.inc.php file:

enable_processing_unique_visitors_multiple_sites = 1
enable_processing_unique_visitors_day = 1
enable_processing_unique_visitors_week = 1
enable_processing_unique_visitors_month = 1
enable_processing_unique_visitors_year = 1
enable_processing_unique_visitors_range = 1

You should now see the unique visitors dimension next to visitors.
