We believe that putting the following code in your WP-Admin > Appearance > Travel Options > General Options > Custom Code within Head Area Box will resolve your problem. We have found this code following That Tutorial
<style>.woocommerce ul.products li.product, .woocommerce-page ul.products li.product, .woocommerce div.product .product_title { box-sizing: border-box; }</style>
Please consider that the Main Styling of WooCommerce Shop is being supplied from WooCommerce Plugin, not from Theme. You can find the Main Stylesheet Here: http://gammatours.org/wp-content/plugins/woocommerce/assets/css/woocommerce.css
We do provide support for our Themes only. There are thousands of Plugins. Is it possible for us to provide support for all of those ?
