Exception Type: TypeError at /admin/cms/page/5/advanced-settings/
Exception Value: __str__ returned non-string (type __proxy__)

Кажется, проблема в том, что value = str(value) не возвращает строку, хотя значениеназывается «Унаследовать шаблон ближайшего предка».Я не уверен, что здесь происходит.

Очевидно, он возвращает тип __proxy__, который, согласно другим вопросам, является типом, используемым для перевода.Что я могу сделать, чтобы это исправить?Мне нужен доступ к настройкам моей страницы, чтобы изменить используемый html-шаблон.

У меня была та же проблема - установка I18N=True в моем settings.py сделала свое дело.

Если это не сработает, попробуйте установить pip django-parler и посмотрите, поможет ли это.
