After I upgrade Piwik to v3.0.0, I get some errors.
I have to disable the Core Plugin “UserCountry” because, if i activate this Plugin, Piwik stop the tracking.
When the Plugin is activated, in the php Error Log I get the Error:
PHP Fatal error: Cannot redeclare class Piwik\Plugins\UserCountry\LocationProvider\DefaultProvider in […]/piwik/plugins/UserCountry/LocationProvider/Default.php on line 0
So, I have to deactivate the Plugin. With that, Piwik is tracking the website user. Without that, if the plugin is active, Piwik determines the tracking of the website User.
