I receive error

"Your order\'s details have changed. Please review the current values and re-submit."

and the page could not be sent.
I don't understand why is the message generated.
On the page can be changed only shipping method. After change is the total amount of order well recalculated.
But after clicking on the button "Confirm order" will be the page reloded and show this Error Message.

thank yo for your help

What template is in use and what, if any, additional order-total modules are being used by the site?
