django - проблема с миграциями и modeltranslations

Question

Я пытаюсь обновить свое приложение, от Django v1.6.11 до v1.7.8. Я следую за instructions to upgrade from South, но получаю снова и снова ту же ошибку. Точнее:

Это, по-видимому, проблема переноса django-model. Я проверил dependencies на своем веб-сайте, и я использую правильную настройку: django 1.7.11, python 2.7.5, django-modeltranslation 0.8.

Примечание: если я удалю Юг из своего виртуального, я все равно получаю ту же ошибку.

Я попытался решить из моего проекта все предупреждения об устаревании, которые я смог найти. Но, тем не менее, ошибка миграции все еще существует. Может ли кто-нибудь увидеть любое возможное решение? Спасибо :-)

UPDATE: после того, как предложение dukeofweatherby, я удалил вызов admin.autodiscover() из моего urls.py. Во всяком случае, после этого я все равно получаю ту же ошибку.
