I’ve recently stopped to receive my EMail notifications so I checked the dashboard and saw that the system stopped tracking altogether. I did the update for Matomo and updated everything on the server.
This is the current version:
Now the system is tracking again, but when I want to send the tracking Email manually I receive the follwing error:
Mysqli statement execute error : Duplicate entry ‘’ for key ‘unique_token’
I have literally no clue what that means. So somebody please help me please
