PHPOpenTracker is a framework solution for the analysis of website traffic and visitor analysis. Tiki provides a template based GUI to phpopentracker so you can see statistics of all sorts about your site.
phpOpenTracker integration is currently NOT working. The work was started but never finished. We announced support for 1.7.
I apologize for this. If you would like to help complete the integration, please contact Marc Laporte
