Django static files not found in production 1.2

My code is working fine in the testing environment (DEBUG=TRUE) but when I switch to DEBUG=FALSE, static files are not being loaded.
To run the application I follow:
python3 manage.py collectstatic --no-input --clear
python3 manage.py runserver
settings.py:

Here, the python3 manage.py collectstatic command correctly fetches my static files and stores it to staticfiles_build/static. However none of my static files are being loaded in production.

However none of my static files are being loaded in production.
do you mean in templates if so you need to load them with {% load static %} template tag
if not... depending on your server you need to configure it to server static files how to do this with Apache and mod_wsgi..
you can read more about How to deploy static files - django docs

csrf token verification error (403) when I try to login as admin since I upgraded django from 1.11 to 2.1.1?

It turns out that the problem is only existing in chrome. I guess I have to make some changes in the settings file regarding csrf_tokens but where ? Please help. Here is my code for urls.py in the main application

from django.conf.urls import url, include
urlpatterns = [
#Admin section url
url('^admin/', admin.site.urls),
#Music section url
url('^music/', include('music.urls')),

Everything was going so smooth with django 1.11, but this unexpected error popped out from nowhere when I migrated and I tried many solutions like setting some values for csrf_domain in the settings file. But, none of them worked. Please help!
Code for views.py file in the music app
from django.shortcuts import render

return render(request, 'music/home.html')

I also didn;t make any changes to admin.

Whitespace matters. Change the following line:
{% if widget.value !=None %}
to
{% if widget.value != None %}

Why won't my models won't show up on admin page in Django?

I have tried everything to try and make this work. I recently tried squashing my migrations and then migrate them again. Alas, to no avail.

blogs/admin.py, not personalblog/admin.py (you can delete personalblog/admin.py file):

admin.site.register(BlogPost)
Also, replace 'blogs' in INSTALLED_APPS with 'blogs.apps.BlogsConfig'.

As you can see in the official release django docs, in version 1.8 things have changed regarding how templates parameters are configured.
TEMPLATE_DIRS has been deprecated, so you can remove it from settings.py.
Instead, in TEMPLATES, set the DIRS key correctly (it is empty now).
For example:
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [os.path.join(BASE_DIR, 'templates'), ], # check the path depending on your prj structure
'APP_DIRS': True,
'OPTIONS': {
'context_processors': [
'django.template.context_processors.debug',
'django.template.context_processors.request',
'django.contrib.auth.context_processors.auth',
'django.contrib.messages.context_processors.messages',
],
},
},
]
