Hi,
I’ve used the Google Analytics Import to move data to Piwik. Unfortunately I run the script twice for a number of days. My idea was to delete the data (I deleted the entries from piwik_archive_blob_2011_XX, piwik_archive_numeric_2011_XX and piwik_log_link_visit_action for this siteid and date range) and rerun the script. After I deleted the rows, the UI view was empty as expected, but after the import run again, the number of visitors was “added” to the old values. How could I delete “all” data for these days?
Thank you very much, Micha
