In GA admin pages I have the universal tracking code. Above it I see this message:
To get all the benefits of Universal Analytics for this property, copy and paste this code into every web page that you want to track.
I'm guessing that once I've copied this code I go into wordpress admin / plugins / google analytics / then select the googleanalytics/googleanalytics.php file and paste the code in to this file somewhere - but where.
Or am I totally wrong. Please reply.
