Php начал изучать недавно и решил попробовать сделать блог. В структуре он вынесен как отдельный модуль в папке vendor в Yii-2. Но с удалением постов возникла проблема! И ищу ошибку уже неделю..
Запускаю Open Server и пробую тестировать блог в разных браузерах по адресу: admin.site.com Так вот..в MicrosoftEdge и Mozilla - все работает и удаляется, а в GoogleGhrome-при нажатии на кнопку удаления появляется звук и после этого всё 'зависает'.

Изначально было такое сообщение, но потом действие с 'unlink'-в function 'beforeDelete' Blog.php - закомментировал. Может быть, здесь нужно применить такой метод с проверкой? Но как это реализовать -не разберусь.
