Not working with Checkout.fi Gateway

Hello,
As first thing, I would ask from you if you can please enable debugging in WordPress, and that you try with minimal plugin setup (WPML+WooCommerce+WooCommerce Multilingual) and with a default theme like Twenty Fourteen – if the issue persists.

Also I would like you to create a new ticket in our forum at wpml.org in order to debug this further thoroughly.
Currently I have no information about this plugin/gateway and his status, and this will be the fastest way to help you.

I also have this problem on the checkout with the 2Checkout Inline Checkout Plugin.

I also posted in the forums on WPML. The issue is definitely with this plugin.

Could you please provide here the link to your ticket?
We can continue debugging this further on the wpml.org forum.

(If costas90 issue comes from the same reason as mine, my ticket is here: https://wpml.org/forums/topic/wcml_endpoints-get_endpoint_translation-returns-for-order-pay/)

@ap.koponen thank you for escalating this ticket. I think it might be related to other issue here on the forums that is already escalated.
Would you mind please to respond to the supporter in that ticket and also provide him a duplicator clone, so that we can investigate the issue further?

Closing this ticket due to inactivity.
I hope that the issue was resolved.
