Why am I getting a TemplateDoesNotExist error in Django 4.0 when the template does exist?

I'm new to Django, and I've been struggling with this TemplateDoesNotExist error for a while. I looked at many other users who were having these issues, but none of the proposed solutions seem to work for me.
Django cannot find my blog/base.html file and claims it looks in '/home/agile/django_project/blog/templates/blog/base.html' for it, but when I check in my ubuntu, it says the directory exists fine?
When I run on my localhost, the site works fine, but when working with ubuntu and Linode is when I run into this problem.
Image of Django error
Image of the path that exists but Django can't find?
Again, I have tried many 'solutions' by adding to template DIRS and stuff but honestly, none have worked. I just don't know what is wrong/how to go about fixing it. Any help I would greatly appreciate.
UPDATE:
I was able to fix it. I accidently put "blog/base.html " instead of "blog/base.html"
Here is my settings.py file, too:

Why Django admin shows different kind of UI interface?

I am new to django, when i created a project and goes to 'url/admin'. It shows the default django admin UI. But now, when i navigate to 'url/admin'. It shows different UI of admin login than default one.
I attached the screenshot of it, how it is looking. How to make this screen to look as default one of django admin screen?
Kindly see the url too in screenshot. Why after 'url/admin' more string shown.

You can use django mongoengine. This is good for basic admin CRUD applications and will quickly get your work done.

Django REST API returning No 'Access-Control-Allow-Origin' header is present with Angular 4

I set up a Django REST API with the Django REST framework, and I'm trying to access it via an Angular 4 front-end. I keep getting an error saying "No 'Access-Control-Allow-Origin' header is present on the requested resource."
I tried installing django-cors-headers, but it doesn't seem to do anything. I'm thinking I may have my REST API set up wrong.

Am I missing something?

You will also need to add CorsMiddleware class to listen in on responses:
MIDDLEWARE_CLASSES = [
...
'corsheaders.middleware.CorsMiddleware',
'django.middleware.common.CommonMiddleware',
...
]
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.

Django 1.11 ignoring tempate trans tag

I've set up everything right, and when I launch:
makemessages --locale fr --locale en
it only takes in account the translation string used in the Python files, not in the template files (NB: I have {% load i18n %} in the first line of all the template files). What did I forget?

You need to use --extensions argument for makemessages to provide your custom extension. By default makemessages process only py, html, js, txt extensions.
