How do I enable Gravatar images in the Activity Log?
Gravatar means Globally Recognized Avatar. When enabled, it will try to find a matching avatar image for your users so you can easily see which user has performed which activity. An avatar image may be shown next to an activity in the activity log.
This feature is not enabled by default as our plugins do not send any of your data or metadata to external web services for privacy compliance.
To enable Gravatar images, log in to Matomo as a Super User and go to Administration > Plugin Settings and enable the Gravatar setting.
