Hello,
1) Is Single Product Builder enabled in Theme Options? If so, you need to add content there, for example – https://prnt.sc/wiswnx , or disable the builder and use one of default Layouts for the single product page.
2) Do you use Elementor? Please provide temporary wp-admin access, we will fix the demo content of the Home page.
3) Do you want to remove the current footer content and have it like on this demo https://xstore.8theme.com/elementor/demos/electronics/?
Regards
