My piwik 1.7.1 installation shows no archived data anymore. I can only see reports for January and February which are still in the piwik_log_-Tables.
Data from the piwik_archive_blob_ and piwik_archive_numeric-Tables isn’t shown anymore. This worked fine for me till Piwik 1.6. With the update to Piwik 1.6 or shortly thereafter i missed the archived reports. I updated my Piwik to 1.7 and 1.7.1 but didn’t get my archived reports shown.
I have cron/archive.sh running and deleted the older entries from piwik_log_visit and piwik_log_link_visit_action every month. The piwik option to purge old visits logs is not activated (it wasn’t yet available when i installed piwik the first time).
The old archive blob and archive numeric tables since 2010 still exist and contain data. Deleting and recreating them isn’t an option as i already purged the old entries from the piwik_log_-Tables.
How do i get piwik to show the data from the archive Tables again?
