Hello,
Search (header builder) has new style http://prntscr.com/qh2vo4
Adding old (full width) design is in our task list. There is no possibility to change it, right now. Follow our changelog – https://xstore.8theme.com/update-history/
Your footer is created using static block – http://prntscr.com/qh2yv7 , so I would recommend you to enable WPBakery Page Builder for static blocks http://prntscr.com/qh2z0k https://www.8theme.com/documentation/xstore/plugins/wpbakery-page-builder/ , then the edit of the footer block will be easier.
Regards
