Application labels aren't unique, duplicates: staticfiles

I'm having trouble figuring out what I'm duplicating here. I'm trying to migrate my files so I can deploy on Heroku. It says that "staticfiles" is duplicated, but I can't see where the conflict is. Does migration need to be done in order to deploy? or is there something wrong with my database?

You need to set a static root which is where Django compiles the static files for serving in production when you run python manage.py collectstatic. The name must be different than the location of your static files in your project.
STATIC_ROOT = str(BASE_DIR.joinpath('staticfiles'))
See the docs for more info.

WSGI application 'mysite.wsgi.application' could not be loaded; Error importing module

I use django 3.1.1 and Python 3.8.5. I want to create simple blog. I use some old code in which programmer used django 1.11 probably, so I change many things, but now I'm stuck
I get error

When I try to remove

I get an error

Some middlewares are obsolet or moved/renamed. Try to use defaut middleware list from django 3:
MIDDLEWARE = [
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
]

I got the same error:
django.core.exceptions.ImproperlyConfigured: WSGI application
'core.wsgi.application' could not be loaded; Error importing module.
When I added the package 'hello' which is not installed in my project to MIDDLEWARE in settings.py:
MIDDLEWARE = [
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'corsheaders.middleware.CorsMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
'hello', # 'hello' package doesn't exist
]
So, don't forget to install the packages which you need before adding them to MIDDLEWARE in settings.py:
pip install <package>

ImportError: No module named menu

I'm trying to customize the admin interface with django-admin-tools.
I'm following https://django-admin-tools.readthedocs.io/en/latest/customization.html
The menu.py has been created successfully with python manage.py custommenu in my project directory.
I have then renamed it to Mymenu.py
When I add ADMIN_TOOLS_MENU = 'project_name.Mymenu.CustomMenu' to my settings.py, as indicated I get the follwoing error: ImportError: No module named menu

I solved it by replacing ADMIN_TOOLS_MENU = 'project_name.Mymenu.CustomMenu' simply by ADMIN_TOOLS_MENU = 'Mymenu.CustomMenu'

I am assuming you have created the app using the following command,
python manage.py startapp custommenu
and then renamed the views.py to Mymenu.py
in that case you need to write custommenu in your installed apps instead of Mymenu

Oscar Dashboard requests /static/css/base.css instead of /static/oscar/css

I'm somewhat new to Django, but I have previously installed Django Oscar on it's own to test it out and it was working perfectly fine.
However I'm now building a project which uses Django-Allauth with a Custom User Model, and I have installed Django-Oscar, however when I launch the Dashboard it doesn't load in it's entirety, (Screenshot of Dashboard) I see from the Run log that it currently requests my static/css/base.css, however when I launched it before I see it goes to /static/oscar/css to get it's stylesheets. I believe that this may be the problem (please let me know if you think otherwise).
I've gone through my settings time and time again to see if there is an issue somewhere but I can't seem to pinpoint anything, so I wanted to post here in help of a resolution.
Thanks in advance.
