If you’re using Total Theme Version: 4.5.1 and Yoast SEO Plugin 5.8 you need to update the yoast.php code in …/Total/Framework/3rd-party/ by replacing wp_seo_get_bc_title with wpseo_breadcrumb_single_link_info. wp_seo_get_bc_title is deprecated as of version 5.8.
This has already been fixed. Please be sure to keep your theme up to date.
If you purchased a valid license of the theme and you ever need support or to report a bug please do so accordingly: https://wpexplorer-themes.com/total/docs/how-to-request-support/
