Hello,
1) Issue with the headers was caused by misprint in custom styles https://prnt.sc/23uhh77 Check now. 2) I have created mega menu using Elementor and disable WP Bakery. Also, I have created footer using Static blocks and disabled Header and Footer plugin. Enabled cache plugin. Check the site speed before https://gtmetrix.com/reports/www.viuvachicvinhos.com.br/e3vP0A0V/ and after https://gtmetrix.com/reports/www.viuvachicvinhos.com.br/so5appO0/
