I’m confused on something. I have 2 different websites, each use a small theme I developed and have the same plugins (all updated). This includes WooCommerce 8.8.3 on both sites. However, the checkout/cart pages look completely different. And the markup WooCommerce uses for each page is also different.

Where is the different markup coming from? I don’t have any theme files overriding WooCommerce!

See the details below…
