sorry still unclear, as i’m a novice and I don’t even understand what is the Piwik URL. I uploaded and activated the plugin. On the WP-Piwik Settings page within the WordPress dashboard. I don’t understand what is my piwik URL, I tried http://mydomain.com/piwik or http://mydomain.com/wp-content/plugins/wp-piwik/wp-piwik.php but just get a blank page, so how do I find out what is the piwik URL?
The Piwik URL is the URL you use to access your Piwik dashboard.
You first have to get and to install Piwik if you want to use WP-Piwik.
See plugin description:
You need a running Piwik 2.0.2 or higher installation and at least view access to your stats. Also PHP 5.3 or higher is strictly required.
Look at the Piwik website to get further information about Piwik.
