Indeed, the same problem here. No visits were tracked anymore.
I added Google Analytics tracking code direct, but still had the same issue.
However since you unlocked the features there is an extra tab “Google Analytics”. There I entered my analytics id and it works. There was an option above to enable/disable something but I didn’t understand because it is in Italian or something.
However I looked at the code and I saw that this is adding the UA code twice. Once with Google Analytics and once called Ginger Analytics??? What is the use of this? Strange.
Also this seams to skew the pageviews data. Suddenly there seems to a pageview extra or even double? Before the avergage pages/sessions was 1,5 and now it’s way beyond 2,5 suddenly.
Please give us an answer.
