Fatal error

Hello,

After I changed a theme a fatal error has occurred. I will be very grateful for any help to get rid of it.

PHP Fatal error: Uncaught Error: Call to undefined function specia_breadcrumbs_style() in /var/www/vhosts/fish-gurman.ru/httpdocs/wp-content/themes/fabify/sections/specia-navigation.php:106
