I dont know if it’s only the last version that show this behavior but i already know that it doesn’t to that on the demo site.
I’ll explain more.
I usally use Piwik to check stats on a day by day basis. I mean, i dont go see them every day; i select a day that i think was my last visit in the calendar and i view stats for each sites that had any visits using links on the multisite and then i advance to the next day until i reach today.
But, today i wanted to see the list of keywords used for the whole year on one of my site so without returning to the multisite i changed the time frame to Year.
Result : No data.
I’ve spent some time trying many different time frames on many sites and it gave the same result, even on the multisite (0 visits).
Then i had an idea, i selected the previous week on one of my sites.
Miracle ! I could see the data.
So, my problem is that if a select an incomplete time frame, one that contain some days in the future, i get no data.
This doesn’t happen on the demo site, for has far as i know.
If you need some “sensible” data like php info, i could send it by email.
Thanks for help and advices.
