Hello,
From the looks of it @paul.r , you just dropped the shortcode into a non-Pro designed page which, as I stated above in the comment from 3d ago,
Edit: I also forgot to mention that the shortcode works if I place it in a default page without an Pro editing done to it. The page breaks only when I’ve edited the page in Pro.
Previously I had designed the page in Pro with the shortcode for checkout used in a row as I’ve done with the My Account, Shopping Cart and other WooCommerce pages and it worked fine.
The checkout shortcode worked previously in that Pro designed page, but now it does not. I’ve updated Pro and several other plugins since the last time I tested the site so I am not sure what has broken the checkout shortcode.
If I have to now use a non designed page then that’s that, but I’m extremely frustrated as the Checkout page worked before when I designed it like the other WooCommerce pages. So I’d like to know why I now cannot design the page where before it worked without problems.
