Hello, Isabel Lima,
Thank you for your response.
Please check how it works when the Advanced layout is disabled in Theme Options >> WooCommerce >> Cart/Checkout Layout.
Provide temporary wp-admin and FTP access.
To provide wp-admin access, you can create a new user account with administrator role via the Dashboard, and provide us with the username and password via the Private Content area.
To create FTP access, please contact your hosting provider for assistance.
Kind Regards,
8theme team
