Hi,
I already asked in the german part
Hopefully you can help me!
My installation runs since march 2010. I set up the cronjob, so the log Data is deleted after 60 days. All reports are safed, and the raw data of the last 60 days.
After I reprocessed the data (http://piwik.org/faq/how-to/#faq_59), I reimported the old tables from a backup.
But unfortunally Piwik ignores this backup-tables and just the data from reprocessing-60 days is viewable.
Does anyone know how I can get Piwik to show everything since march 2010?
I would be really happy
