I just found a serious bug in my piwik installation. I am using the version 0.5.5 (german). In my dashboard I have included the widget “Visits summary/Grafik der letzten Besucher”. Everything works well so far. But when I change the date schedule from day to e.g. month and then year, week etc. piwik seams to loose data and don´t show the correct values ! I could see that sometimes the widget will NOT show any values, sometimes there is only showing value from the past ! This will even happen when I change the date schedule by pressing “Woche”, “Monat”, “Jahr”, “Tag” or choosing a date by calendar.
Does anybody have the same issues ?
