Hi,

Hope you can help me out here 

Whenever I'm checking out on my website, after choosing the payment method and accepting the terms and conditions, the button "Order with obligation to pay" is disabled. The error message is: 

"Please make sure you've chosen a payment method and accepted the terms and conditions." but this is all done.

Do you know how to solve it?

Thank you very much!
