Enhanced eCommerce tracking

This plugin is totally new to me. I’ve never used GADWP.

I’ve selected Enhanced Ecommerce Plugin on the integration page and I can see ga('require','ec'); in the page code, but when I make test purchases, I don’t see them in Analytics.

Does this feature require any special setup or another plugin?

Please note I’m using a cached copy of analytics.js, not directly from Google, but sales are not registered even after updating the file.

The page I need help with: [log in to see the link]
