Hi, we are using piwik for quite a while now, I would say few years … and I think before march 2012 …
but the calendar stuck to mars 2012 and if I check the mysql base, I can see table piwik_archive_blob and piwik_archive_numeric going back to 2001
how can I find those old data in piwik ?

Thanks !

Stéphane

Check in the piwik_site table that the ts_created field is set to the original date?

Thanks, this solve the calendar selection problem but no data are shown … I checked inside the tables and they are empty …
