В моей теме код breadcrumbs выглядит так:

Код:

//hook for get disqus count
if(!function_exists('tm_get_disqus_count')){
    function tm_get_disqus_count($count, $post_id){

Помогите применить описанное решение к этому коду, понимаю что это несложно, но у самой не получается.

Я сделал обрезку заголовка только в самой записи, на 10 символов, изменить количество знаков можете в коде: $chars_limit = 10;
Делал на скорую руку, если будет ошибка, отпишитесь.

Я сделал обрезку заголовка только в самой записи, на 10 символов, изменить количество знаков можете в коде: $chars_limit = 10;
Делал на скорую руку, если будет ошибка, отпишитесь.

Если копировать код целиком - страница выдает белый экран.

Вставила отдельно только ваши правки - вроде работает. Копаю дальше, благодарю.

Помогите с php кодом breadcrumbs WP
