Checkout process fails in Pro version – Translatepress

Hello!

I contacted you via the contact form on your website, but haven’t received any replies for a week. I’m using the PRO version of the plugin. I’m really happy with the functionality, however it has a serious bug. When using Translatepress plugin, it throws an error when trying to submit the order. The order itself goes through, but the user is stuck on the checkout page with the error message. Strange thing is that the free version doesn’t have this problem and everything works as it should. It’s the pro version which is having this issue.

Please check and help me to debug this issue.

Thank you!
