I created a custom theme and woocommerce shortcodes dont seem to work. For my single product and archive products I edited the files from the plugin folder but for the cart and checkout I had to create a custom page template. For my cart I just copied and pasted the cart.php file from the plugin folder into my cart page template but that doesnt seem to work with the checkout page. How do I get the checkout page to work? Is there certain steps I should do before since my theme is a custom theme?
