I recently noticed that if I select the period ‘year’ the data for 2015 don’t show up (There is no data for this report). But the monthly view does show all the visitors except for july '15 (again ‘There is no data for this report’). And again, if i choose the weekly view for july '15 I can see all the visitors.
So the data ist in the DB. What is going on there? How can i solve this?
I updated my piwik installation to 2.16 two days ago, but the problem is older than that.
Thanks for help, best regards
