The site is http://www.juicysatsuma.com/ and I'm certain the Tracking ID is correct.
There are no errors in the network log or the console. I can see Google being pinged when I refresh the page, and when I interact with the site (I have a couple of events set up). GA reports show not page hits, no events, and nobody on the site. The tracking ID statis under GA properties is 'Tracking Not Installed'.
It's the first time I've used GA since they moved from ga.js to analytics.js. I never had this problem before, but I'm not ready to move back to old code.
