Django debug toolbar loads but doesn't show on the local server even after proper installation

I have installed django debug toolbar correctly on a pipenv environment and done the main steps, such as adding internal_ips of 127.0.0.1 and adding the debug toolbar to installed_apps and middleware but still whenever I run the server and open a template of an app the debug toolbar doesn't show.
However if I open the page source in the browser, it shows all the list elements of the toolbar however the toolbar doesn't display, does anyone know what is going wrong and how I could fix it.
This are the changes made to the settings.py file:
import mimetypes
mimetypes.add_type("application/javascript", ".js", True)
mimetypes.add_type("text/css", ".css", True)
mimetypes.add_type("text/html", ".html", True)
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'playground',
'debug_toolbar',
]
MIDDLEWARE = [
'debug_toolbar.middleware.DebugToolbarMiddleware',
'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',
]
INTERNAL_IPS = [
'127.0.0.1',
]
And the following changes to the urls.py folder:
import debug_toolbar
urlpatterns = [
...,
path('__debug__/', include(debug_toolbar.urls))
]

How to add 'django.contrib.auth' app in django

I deployed Django project using cloud code from pycharm.
but in this sample template, there were not the code in installed_app basic apps like these
'django.contrib.admin', 'django.contrib.auth',
'django.contrib.contenttypes', 'django.contrib.sessions',
'django.contrib.messages', 'django.contrib.staticfiles',
there was only 'django.contrib.staticfiles' apps.
Also the default middleweres were not completely installed
INSTALLED_APPS = [
'django.contrib.staticfiles',
'helloapp',
]
MIDDLEWARE = [
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
]
So, is there any way to use default apps to make login page.?

cross origin access issues - django 2.1.7

I have gone through literally all SO links, reinstalled django and django-cors-headers and followed this to the T and yet we get
pre flight error cross origin not allowed
Django version 2.1.7
relevant sections of settings.py
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'corsheaders',
'uploads.core',
]
MIDDLEWARE = [
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'corsheaders.middleware.CorsMiddleware',
'django.middleware.common.CommonMiddleware',
'corsheaders.middleware.CorsPostCsrfMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
]
CORS_ORIGIN_ALLOW_ALL = True

CorsMiddleware should be placed as high as possible, especially before any middleware that can generate responses such as Django’s CommonMiddleware or Whitenoise’s WhiteNoiseMiddleware. If it is not before, it will not be able to add the CORS headers to these responses.
MIDDLEWARE = [
'corsheaders.middleware.CorsMiddleware', # <-- should be at the top
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
'corsheaders.middleware.CorsPostCsrfMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
]

This is an issue is because the given Django package is for Djangov2.2>
Here you are using 2.1 so it doesn't support it.
You need to manually pass headers from HttpResponse

No 'Access-Control-Allow-Origin' header is present on the requested resource.

I am using ajax to call the following url:
"https://www.bittrex.com/api/v1.1/public/getticker?market=usdt-btc"
I am getting the following error:
No 'Access-Control-Allow-Origin' header is present on the requested resource.
I have installed django-cors-headers and my settings.py looks like this:
INSTALLED_APPS = (
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'corsheaders',
'crispy_forms',
# The following apps are required:
'django.contrib.sites',
'allauth',
'allauth.account',
'allauth.socialaccount',
'allauth.socialaccount.providers.google',
)
MIDDLEWARE_CLASSES = (
'django.contrib.sessions.middleware.SessionMiddleware',
'corsheaders.middleware.CorsMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.auth.middleware.SessionAuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
'django.middleware.security.SecurityMiddleware',
)
CORS_ORIGIN_ALLOW_ALL = True
CORS_ORIGIN_WHITELIST = (
'http://127.0.0.1:8000',
)
Why am I still getting the error?
** I have read all the other answers related to this but they have not helped me. I have used the chrome plugin too and it does work with it but I want a solution without it **
Django Version = 1.8

The configuration looks fine and according to the documentation. I just compared it to my configuration and it's almost the same. Since I use my API for only one website, I have it configured in my CORS_ORIGIN_WHITELIST, you can try this also to see if it responds.
Also, try removing all python cache files and restart the application server, maybe the setting where not loaded.

It is not your app issue i.e. django issue as CORS is a http header which let's a user agent gain permission to a resource which is on a different domain as that of yours. It is a browser issue, hence adding CORS application in django will have no effect.

Try adding crossDomain: true in the ajax request

Unable to login to the admin panel in Django

The site is working fine but when I switch to http://127.0.0.1:8000/admin/ it shows AttributeError at /admin/ .I tried to include MIDDLEWARE_CLASSES in the mysite/settings.py but to no avail . Here are some details :
Django mysite.settings
INSTALLED_APPS = [
'personal',
'blog',
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
]
MIDDLEWARE_CLASSES = [
'django.contrib.sessions.middleware.SessionMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.middleware.security.SecurityMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.SessionAuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
]
http://127.0.0.1:8000/admin/ page ::
Django mysite.urls ::
from django.conf.urls import url, include
from django.contrib import admin
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^', include('personal.urls')),
url(r'^blog/', include('blog.urls')),
]
Am I missing something? Ask for more info if required .
Thanks!

You should know that altering the order of the middlewares can cause serious problems, which it did in your case.
So my advice to you is to add your apps at the end of the INSTALLED_APPS and create a new django project and replace your middlewares list with the middlewares list of the newly created project or try with these
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',
'django.middleware.locale.LocaleMiddleware',
]
