Tracking not working in Piwik 2.16.5


I’m implementing Piwik to track four websites at the same time. Three of the four websites are working smoothly, without any major issue. The fourth one however seems to dislike piwik: I’m not collecting data wether using the script or the Image Tracker code .

When I’m implementing the script, the consoles of my browsers indicate that some part of the Piwik code does not work properly, indicating that window.Piwik.addTracker is not a function (the error code is below):

[Error] TypeError: window.Piwik.addTracker is not a function. (In ‘window.Piwik.addTracker()’, ‘window.Piwik.addTracker’ is undefined) (anonymous function) (piwik.js:69:278)

The page is here: In the meantime, the same piwik install works perfectly on and on the two other websites…

I can’t figure out why it’s doing this… any clue?

I’m on the latest stable version of Piwik (2.16.5) installed on an OVH shared hosting plan.
