How can I fix the following error NoReverseMatch at /blog/index/ - django

Question

I am getting the following error
NoReverseMatch at /blog/index/
and
Reverse for 'feed_articles' with arguments '()' and keyword arguments '{}' not found. 0 pattern(s) tried: []
just because I deleted/commented out a url I know longer need. The url isn't blog/index either. something tells me it's an ordering issue because I've had that happen before in my django app. But I am confused. Heres what I commented out
from django.conf.urls import url, include
from . import views
urlpatterns = [
url(r'^$', views.post_list, name='post_list'),
url(r'^index/$', views.index, name='index'),
url(r'^video_submission/$', views.video_submission, name='submission'),
url(r'^contact/$', views.contact, name='contact'),
url(r'^privacy/$', views.privacy, name='privacy'),
url(r'^dmca/$', views.dmca, name='dmca'),
url(r'^terms/$', views.terms, name='terms'),
url(r'^search/$', views.post_search, name='post_search'),
url(r'^create/$', views.post_create, name='create'),
url(r'^images/$', views.static_images, name='static_images'),
url(r'^video_agreement/$', views.video_agreement, name='video_agreement'),
### url(r'^feed_articles/$', views.articles_list, name='feed_articles'),
url(r'^feeds/$', views.feed_list, name='feed_list'),
url(r'^feeds/new$', views.new_feed, name='new_feed'),
url(r'^(?P<id>\d+)/feed_delete/$', views.feed_delete, name='feed_delete'),
url(r'^(?P<id>\d+)/article_delete/$', views.article_delete, name='article_delete'),
url(r'^tag/(?P<tag_slug>[-\w]+)/$', views.post_list,
name='post_list_by_tag'),
url(r'^(?P<slug>[\w-]+)/$', views.post_detail, name='post_detail'),
url(r'^(?P<slug>[\w-]+)/edit/$', views.post_update, name='update'),
url(r'^(?P<id>\d+)/delete/$', views.post_delete, name='delete'),
How can I correct my syntax so that this minor issue will work?

Find the template that is being rendered by whichever view is being called when '/blog/index/' is requested, and look in that template for {% url 'path_to_this_urls_file:feed_articles' %}. Also look in any templates which that template extends and/or includes, including template tags.
