Setup:
OPC 1.2
zenCart 1.54
Responsive Sheffield Blue 2.0
Braintree

I started to have this problem this weekend. Before it was working fine. I believe I had an earlier version when I mysteriously started to have this problem. I installed version 1.3 and got another message saying Can't use this method and a link to the zencart 3 page checkout. So I installed version 1.2 and now still have the original message "Your order's details have changed. Please review the current values and re-submit" and it continues to loop.

Any help will be appreciated. Need any additional information. Just let me know.

The highlighted message that you received using OPC 1.3.0 is most likely indicative of the issue you're having. Your store apparently has a jQuery conflict that is not allowing OPC to do its thing. That's why that link to the 3-page checkout is there, so that your store can continue to generate business while you're sorting out what those issues/conflicts are.
