SEOPress Breadcrumbs Filter
You can use below code to functions.php or any plugin to make it work.
add_filter('seopress_pro_breadcrumbs_crumbs', 'cww_breadcrumbs_crumbs');
function cww_breadcrumbs_crumbs($crumbs) {
//$crumbs is a multidimensional array.
//First array: key=position, second array: 0=>page title, 1=>URL
//do your stuff
foreach ($crumbs as $key => $crumb) {
// apply do_shortcode to breadcrumb title
$crumbs[$key][0] = do_shortcode($crumbs[$key][0]);
}
return $crumbs;
}
