[Fixed]-Using the URLconf defined in TEST_PAGE, Django tried these URL patterns, in this order:

By including ‘TEST_PAGE‘ twice(in both urls.py), you have defined a url:

/TEST_PAGE/TEST_PAGE

So

django can find url /TEST_PAGE/TEST_PAGE but not /TEST_PAGE

Your Mysite/TEST_PAGE/urls.py should be:

from django.conf.urls import url
from . import views

urlpatterns = [

    url(r'^$', views.index, name='TEST_PAGE'), # maps to /TEST_PAGE/
]
