Hi I am totally lost,
I installed Piwik on one of my wordpress sites a few months ago. So today I logged into piwik and tried to enter anther website.
So first I go to Settings and add my new wordpress website url.
I then go to add that url and install the Piwik plugin.
Then I go to Piwik settings in the plugin and enter the Piwik URL (REST API): as http://www.mydomain.com/analytics/piwik/
Then I enter the Auth token: Which I got from clicking on API in my original Piwik login panel
I then get the this An error occured: Please check URL and auth token. You need at least view access to one site. [Support]
