When using YITH to display the wishlist in the my-account endpoint of WooCommerce, the wishlist works fine, but the endpoints stop working. If we change the page to anything else other than the my-account endpoint, the problem goes away.
Go to Woocommerce->Status->Create default WooCommerce pages
Click button "Create pages" and they'll renew. (Notice: before that, delete the Wishlist Page for the confidence.)
