Hello,
First of all thanks for choosing our Theme, we are glad to be you in the WoodMart WordPress family :)
Please make sure that you have created a page for the my-account and set it as the Woocommerce my-account page from WooCommerce >> Settings >> Advanced.

Note: The pages must contain shortcodes.
MyAccount shortcode: [woocommerce_my_account]
Cart Shortcode: [woocommerce_cart]
Checkout Shortcode: [woocommerce_checkout]
Do the same for the cart checkout pages then clear cache and check back.
Best Regards.
