Hello,
sorry for the late reply.
As we can see all your demo content imported fine (posts, pages, menu,…), everything except images because we cannot share them and we replaced them with placeholders. You just need to replace that with your own images.
You still have to go through the basic WordPress settings, things like:
– saveing menu to Theme location
– upload logo, favicon and other things inside Customizer
– start to create your own content
I hope this has been helpful.
Best Regards
