Answer 2

A little late but better than nothing. I am using Wordpress 4.4.2 and WooCommerce plugin 2.5.5 and have the same problem when checkout.

Please take a look at this solution: https://wordpress.org/support/topic/json-error-on-checkout-page/page/2#post-8159100 .

Summary: Open file checkout.min.js in /wp-content/plugins/woocommerce/assets/js/frontend and put string
