Белый экран при редактировании ресурса

Здравствуйте!
Столкнулся с проблемой — при редактировании ресурса возникает белый экран.
Система позволяет редактировать чанки, сниппеты, файлы, но при попытке отредактировать ресурс возникает ошибка.

Кеш чистил, папку cache удалил — не помогло.

Версия MODx 2.3.2 pl
