Django CMS-не удается загрузить изображения через cmsplugin filer image

у меня проблема с локальной установкой на django cms 2.3.3: я установил его через pip, в отдельном virtualenv. затем я следил за учебником для settings.py конфигурация, я запустил сервер. Затем в admin я создал страницу (home), и я попытался добавить изображение в заполнитель через cmsplugin_filer_image, но загрузка кажется, что не работает. вот мой settings.py:

когда я пытаюсь загрузить изображение в буфер обмена раздел я не имейте эскиз, но просто "неопределенное" сообщение:

и это консоль runserver при попытке загрузить:

[20/Oct/2012 15:15:56] "POST /admin/filer/clipboard/operations/upload/?qqfile=29708_1306856312320_7706073_n.jpg HTTP/1.1" 500 248133

[20/Oct/2012 15:15:56] "GET /it/admin/filer/folder/unfiled_images/undefined/ HTTP/1.1" 404 1739

кроме того, это файловая система проекта:

поэтому файлы загружаются, но они недоступны для cms. есть аналогичный вопрос здесь, но не помогает мне так много. Было бы очень полезно любую помощь по этому вопросу для меня.

- спасибо, люк
