Hi There,
You have to set the page for the posts page first under Settings > Reading:
And also change the title of that page to Learning Center.
After that adding this custom code under functions.php file locates in your child theme:
add_filter('x_breadcrumbs_data', 'post_parent_trail', 9999999, 2);
function post_parent_trail ($crumbs, $args) {
if ( is_singular('post') ) {
$category = get_the_category( get_the_ID() );
if ( count( $category ) > 0 ) {
$crumbs[1]['label'] = $category[0]->name;
$crumbs[1]['url'] = get_category_link( $category[0]->term_id );
unset($crumbs[2]); //to make sure category won't duplicate
}
}
return $crumbs;
}
Hope it helps
