I Installed Piwik 0.4.2 and everything was fine until, some weeks later, I updtated to Piwik 0.4.3 and started the auto archiving cron job.
After that the reports peaked at 1000+ visits and showed lots of weird data for that day:
ring bourguesan ffb
soumettre un site orange
It seems like it includes the Piwiks instalation data in the rports.
Can anyone point out a reason for this and how can I remove this data from the DB?
