Just upgraded to version 0.6 and everything seemed to work well. When looking closer at the charts I recognized that no data before may 2010 is displayed.
What I tried to solve this:
- deleted all piwijk_archive_* tables and let piwik recreate those tables and contents
- verified that table piwik_log_visit contains data before may 2010
Any suggestions what to do? Need more info to debug this problem - ask me?!
Update: The date picker (calendar symbol) does only offer one date: 5th of may 2010… weird!
