I started a website building project with Django, but ran into a problem with the WSGI server and but I haven't change anything
Please, anyone who knows the answer, let me know.

raise ImproperlyConfigured(
django.core.exceptions.ImproperlyConfigured: WSGI application 'DjBlog.wsgi.application' could not be loaded; Error importing module.
I have searched and tried many ways, but I could not find the right one.
Change django_project.settings with DjBlog.settings in your wsgi.py file.
Then follow the below steps to overcome ModuleNotFoundError.
Step 1: Install the app django-cors-headers
pip install django-cors-headers
Step 2: Add corsheader to the Installed App list in settings.py
INSTALLED_APPS = [
...
'corsheaders',
...
]
Step 3: Add CorsMiddleware and CommonMiddleware to middleware list in settings.py
MIDDLEWARE = [
...
'corsheaders.middleware.CorsMiddleware',
'django.middleware.common.CommonMiddleware',
...
]
Step 4: Allow access to all domains by just Adding the following variables in settings.py:
ALLOWED_HOSTS=['*']
CORS_ORIGIN_ALLOW_ALL = True
