lately I have updated the Piwik installation to the latest 1.7.1 version, in 4 different websites, and in all of them, suddenly, the Live Plugin started misbehaving - the widget in the dashboard shows entries of March, 18th as if they have been just made.
Something similar happens in the Visitors’ Log.
If I select, say, yesterday, I do see entries from March, 20th, or if I select the 19th, I see entries from the 19th. But selecting today (21st) it shows all entries from 18th, 19th, 20th and 21st together in the same page.
I’ve checked whether the latest updates have been applied, and so it seems (checking the 1.7-b1.php file in the Updates folder against the actual state of the database).
Apart from that, all the rest seems to be working fine.
Any idea about how to proceed to investigate the issue?
