Curcy Pro – error 500 when finishing the order

When the plugin is turned on and users choose bank transfer in chekout page, it throws an error 500 at ?wc-ajax=checkout request.
There’re two ways of payment – bank transfer and PayPal. Second one works properly. Bank transfer won’t let users to order confirmation page and don’t send the confirmation email. No matter which currency is chosen – default or additional.

When the Curcy plugin is turned off, everything works correctly.
