WooCommerce: Getting stuck at End-point "Review Order" after update to 2.1.2

Hi there,

We recently upgraded to WooCommerce version 2.1 and had everything working perfectly when we launched the site yesterday, including all pages/end-points from shop through to checkout.

I then saw an update, and upgraded to 2.1.2.

I don’t know at what point after upgrading to 2.1.2, but customers are now unable to get through the payment section in particular “end-point” Order Review.

This isn’t an issue with the general upgrading to 2.1 as it worked fine up until yesterday.

WooThemes or anyone for that matter, please advise what we should do as I am at a loss.

We are also getting these errors on the back-end:

Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, ‘wc_setup_product_data’ was given in /home/content/13/3680913/html/wp-includes/plugin.php on line 507

Any help will be much appreciated.
