Just installed Piwik and love it. Will definitely stay with it as it beats GA or manually having to download/run PDF reports with a Windows software from server log files.
What other files needed to be public (accessible) in order for me to give all these CMS plugins the API access needed? Or better open the Piwik install and limit Piwik access by sites’ IPs? All sites and Piwik are on the same server.
