I have the same problem. The checkout page seems corrupt. I got the pro plugin from fluid checkout and it only works with twenty one theme. with woodmart child seems broken. Could you please take a look at the screenshots?
We just checked your checkout page and it seems to be working correctly. Here is a screenshot https://gyazo.com/9dc273dd008d5c4dd86e89d827d83593
Could you please clarify where we can see this issue on your website?
I got the answer: meanwhile we got into the Layouts section and turned off the checkout layouts. This was the conflict with the other checkout plugins. Now it’s working 🙏🏼💪🏻
