Hello,
These membership pages (like login, logout, account, register, password reset etc.) relate to woocommerce. Pages should be imported together with demo content (make sure you have checked all the server requirements before the theme installation – https://xstore.helpscoutdocs.com/article/60-xstore-theme-requirements). If you don’t have these pages, please install them via WooCommerce > Status > Tools tab. Unfortunately, I can’t login to help you with this – https://prnt.sc/jas9uf
