No price indication anymore in google analytics

Nicolas,

I understand reading this thread that the GA Ecommerce variables will be passed to Google only when the order is changed to status 'Confirmed'.

In which of the below options is GA Ecommerce activated? Am I missing other options?
1. When the admin changes the status in the backed
2. When Paypal automatically request the call-back URLs to change order status
3. When the user is redirected to the Thank you page

In my current set-up, there is no Google Analytics script in the back-end, and I have a browser plugin to deactivate myself from GA tracking in the Front-end.
Our customers should be tracked by GA in the front-end but we see no revenue coming in GA interfaces.

Both 1 and 3 sends the data to GA.

If you don't see the statistics, turn on the debug mode option of the GA plugin.
Then, while doing the purchase on the frontend open your broswers javascript console and it should display the status of the submission of the order data to GA when returning to the website after the payment. So you'll be able to see if there is something wrong with the way you setup the GA plugin or with the GA account itself or something else (javascript errors on the website could prevent the GA code to be triggered).
Of course you need to have the tracking plugin disabled for that in your browser or try with another browser.
