Hi Charlie,
I think I have stumbled across a Woocommerce Checkout page bug. This has been happening in all 6.7.x releases - I am on 6.7.2 (the latest) I am getting the iframe response error.
This is happening on every website I have (my own and clients) with Woocommerce installed.
Please try the following steps to see if you get the same behaviour:
- Open the Checkout page in Cornerstone - you should get the error screen shown above.
Next:
- Revert the Checkout page to default Gutenberg with the
[woocommerce_checkout]
- Go to any Product’s public page and add it to cart (possibly also attempt to go Basket > Checkout - it should work).
- Go to Cornerstone and edit the Checkout page.
- With a product in the Cart, Cornerstone the Cornerstone Checkout page will load.
Can you replicate this? I expect so.
Thanks,
Christopher
