Hello,
I can’t see your site – https://prnt.sc/1sjlu0j Contact your hosting provider and ask about assistance.
About the Footer: Do you import Elementor or WPBakery demo content on your site? Enable Elementor for static blocks https://prnt.sc/1sjm6cr , then you will be able to edit the content. Do not use 2 mentioned plugins at the same time to edit content, it may cause a mess.
Regards
