When I look at Visitors / locations & providers / Country (Geo IP) the visitor locations are listed correctly but on the dashboard ‘visitors in real time’ widget the countries are still incorrect (for example 5 of the last 9 visitors incorrectly showing as USA when in fact they are UK).
No. The Live widget doesn’t use the same columns as the GeoIP plugin. We’ll fix this when the GeoIP plugin is included with the core piwik distribution.
