Having a bit of a problem with the checkout in WooCommerce. Just after a customer puts in their billing details and ticks the box to ship to billing address then clicks Place Order the page refreshes and gives a "Invalid Shipping Method" error.
We have Free shipping enabled for orders over £50 and it is set to default to that as soon as the order reaches that amount. So no other options are available, which is what we want. We thought at first it was something to do with that but even if the order is under £50 and we choose the correct shipping method we still get the error.
Has anyone else come across this and if so did you find a solution?
Woocommerce version is 2.0.13 and WordPress is 3.6
Theme is Mystyle by WooThemes version 1.2.7
