Hello, @Ms Morbenia Morbeck,
Your provided WordPress access is a vendor access see the image: https://postimg.cc/JtZmcqNt with this vendor access I am not able to install the theme and import the demo for you because I am not able to access the WordPress admin dashboard. How can I import the demo and set up the theme? I was asked for super admin access. Please share the super admin access with us in the private content area of this topic so that I will check and help you out.
Regards 8Themes Team.
