Currency conversion after checkout results in HTTP 405

[askmeegs]

If you click "place order" in the UI with items in your cart, and the success page shows up, then from that success page, try to convert the currency in the top-right, I see an HTTP 405 error.

Solution - make sure the order success page handlers + HTML template are configured to support currency conversion

I think this is happening because when you change currency, you get redirected to /cart/checkout but with a GET request. However that endpoint does not support GET.

I think the best option would be to hide the currency conversion form on this page through a template variable.

Thanks for finding this.
