addTracker not working

I am using Piwik 2.16.0 and am trying to implement the addTracker feature, however, I am getting the following JavaScript error:

TypeError: M[Z] is undefined

and points to line 22, col 349 of piwik.js

Any ideas as to why this is not working?

please try with Piwik 2.16.2 as this should work :+1:
