Я пытался сделать много вещей, которые я нашел здесь, но ни один из них не дал мне желаемого результата. Кроме того, ошибки, которые имели вопросы, не были такими же, как этот. Я также просмотрел много постов в Интернете и все еще не мог найти ответ. Пожалуйста, посмотрите это, и я был бы очень признателен, если бы мог получить ответ.

Вы не установили blog в INSTALLED_APPS.

Вам нужно изменить INSTALLED_APPS на что-то вроде этого: 

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'blog.apps.BlogConfig'
]

Это не связано с вашим конкретным вопросом, но просто хороший совет, если вы продолжаете публиковать в переполнении стека. НИКОГДА не делитесь своим секретным ключом, который вы только что сделали, когда отправили свой settings.py.

Есть ли у вас приложение под названием Блог? Я надеюсь, что вы забыли добавить его в INSTALLED_APPS

я думаю, что вы забыли добавить имя приложения в список установленных приложений в settings.py
