Я настраиваю новый сервер и хочу перенести проект с Laravel версии 4.0 на Laravel версии 5.2
Я выполнил шаги, упомянутые в этом URL Обновление с Laravel 4 до Laravel 5
но выполнив все шаги, получил ошибку
[Symfony\Component\Debug\Exception\FatalThrowableError]
Fatal error: Class name must be a valid object or a string

В чем может быть причина?
