Why do I receive no Geotargeting options for delivery limitations after installing a paid MaxMind GeoDB, but I did when I was using a free DB?
If you have purchased a MaxMind database for a specific country or region, rather than worldwide, then OpenX might not realize that your database is fully working. This is because OpenX is testing the database against a pre-supplied IP which is located in the USA. If your database can’t resolve the city information of the IP, then city targeting options won’t be available. To fix this, go to your Geotargeting settings page and tick the box for “Show geotargeting delivery limitations even if GeoIP data unavailable” – make sure to submit the page after changing the option.
