I have tried doing a lot of things which I found here but none gave me the desired result. Also, the errors which the questions had were not the same as this one. I also looked at a lot of posts online and still couldn't find the answer.
Please see this and I would be highly obliged if I could receive an answer.

Answer 1

i think you forgot to add application name in installed apps list in settings.py

Answer 2

You have not installed blog in INSTALLED_APPS.
You need to change INSTALLED_APPS to something like this:
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'blog.apps.BlogConfig'
]
This is not related to your specific question, but just good advice if you keep posting on Stack Overflow. NEVER share your secret key, which you just did when you posted your settings.py.

Answer 3

Do you have any app called Blog? I hope you have forgotten to add it to the INSTALLED_APPS
