they originally have been piwik installations and have been updated.
Right now Matomo is not running properly.
Report etc are all empty.
check attached images. on the front dashboard you can see, that i get a lot of visitors, with the country, the OS, etc shown. on the subpages nothing is shown.
So it seems like you are properly recording the data, but no reports are generated out of this.
So please check if your cronjob is still running correctly and it’s log isn’t showing any errors. (If you haven’t a cronjob set up, you need to have browser archiving enabled, but for larger instances, I wouldn’t recommend this)
