We recently migrated our blog to a new host with a new URL name. When I run P3 I follow all the guidelines in the help section that say to circumvent cache plugins (we aren't running a cache plugin) and use my IP address (I've checked it and it matches). I'm still getting zero visits and no data. Do you think I need to manually delete the tables in my db to completely wipe out the older version? If so, what are those tables named?
