Какой механизм удаления постов в Yii2? В проекте блог вынесен как отдельный модуль. Если удалять в админ.панели в backend пост, то debage не фиксирует ошибок, приходится закрывать страницу через диспетчер задач, т.к. браузер зависает, и посты удаляются только в базе.

BlogController (блога в vendor)

Если закомментировать 'beforeDelete' в Blog.php- зависает.

Все перепробовал, но вот что интересно: В GoogleChrome - зависает, а в Microsoft Edge - пост удаляется как надо!
В чем причина здесь?

В Yii никакого блога нет. Проблема в вашем коде.

Это понятно, что в коде-где же ещё может быть?
В Yii2 есть возможность сделать блог как отдельный модуль в папке vendor, что я и пытаюсь реализовать.

В Мicrosoft Edge и Mozilla посты удаляются, а в GoogleChrome - он как-бы 'зависает'.

Сейчас Blog.php выглядит так:
<?php

namespace medeyacom\blog\models;

use common\components\behaviors\StatusBehavior;

use yii\behaviors\TimestampBehavior;
use yii\db\ActiveRecord;
use yii\db\Expression;

use yii\web\UploadedFile;
