we have a problem, after updating piwik from 1.x latest version to 2.1.x (latest) version, we can’t get Visitor logs before 2014-02-24 rendered.
Visits log page says “no data for this report”, and “frequency overview” widget stills empty with zeros.
Looking for data into piwik_archive_numeric_2014_02 table, data stills there.
We haven’t any http/php error, neither after debug settings activation.
Any help would be appreciated.
