I've installed Piwik 2.0 and almost everything is running great.
Using 2 different browsers I viewed my site (piwik is monitoring), then went to the dash board to look at the stats. Information look correct on pages viewed time etc. But in the 'Visitor Map' it showed the country as the USA. Great, but I live in the UK and the web-server is located in the UK. I scanned for setting country location in preferences etc... in Piwik and WordPress what am I doing wrong?
