Проблемы с MIGX. Ошибка 500

Здравствуйте.

Примерно с неделю назад в MODX случился какой-то баг. Без каких-либо предварительных действий перестал авторизовывать пользователя admin, ссылаясь на неправильный пароль. Изменения в базе данных приводили к тому же результату, письма на почту не приходили.

Почистили salt, session и unblock в таблице modx_users, почистили кеш, задали новый пароль через базу — и проблема решилась. Но после авторизации — не работают поля MIGX. Вернее, код сниппетов отрабатывает на сайте, и в админке таблицу видно (частично), но при добавлении или редактировании элементов MIGX — загружается пустое окошко с бесконечным Loading.

Если перейти в верхнем меню (там где установщик) в раздел MIGX, то выдает Ошибка. Код 500.

Переустановка MIGX ничего не решила.
