We have just done a bit more digging and done a short term fix by removing Portugal from the list of countries that a state field is not show in the class_wc_countries.php file.
Problem resolved. It was running W3 Total Cache in conjunction with Woocommerce. See: http://docs.woothemes.com/document/configuring-caching-plugins/
I’m getting a similar issue. My site works ok in Chrome, but the add to cart button is not working correctley in Internet Explorer (I’m running IE10). When you press add to cart the button the basket page is coming up in IE saying the cart is empty.
I’ve tried numerous themes including TwentyTwelve and Wootheme’s Mystyle and it’s not working.
Frustrating to say the least.
