Hello,
I can see 3rd party plugins on your site, they can be reason for the problem with import.
I’ve disabled WPBakery plugin, because you imported Elementor demo content. Do not use both plugins at the same time.
Appearance > Widgets > Footer > correct static block selected. Also, Elementor was activated for static blocks, so you can edit Footer static blocks now – https://xstore.helpscoutdocs.com/article/47-static-blocks
Headphone demo version uses Multiple headers – https://gyazo.com/f214194b63fbec6e7f864ea4a2ebe61a
Check your site now. Let us know if you need any further assistance.
Regards
