I have noticed when switching between day and week and month using Actions.getPageUrl the nb_uniq_visitors is removed for anything other than period=day.
I have tried editing the config.ini.php to:
enable_processing_unique_visitors_day = 1
enable_processing_unique_visitors_week = 1
enable_processing_unique_visitors_month = 1
enable_processing_unique_visitors_year = 0
enable_processing_unique_visitors_range = 1
and then dropped all piwik_archive_* tables from the database.
Do I now have to wait a week or a month for this to start showing back up or will it not show?
Cheers
Oliver
