Ошибка сервера Django (500), когда DEBUG = False

Question

settings.py

ALLOWED_HOSTS = ["localhost", "192.168.0.7", "127.0.0.1"]

MIDDLEWARE = [
    'django.middleware.common.BrokenLinkEmailsMiddleware',
    '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',
]

STATICFILES_DIRS = [os.path.join(BASE_DIR, 'static')]
STATIC_ROOT = os.path.join(BASE_DIR, 'static_collection')
STATIC_URL = '/static/'
MEDIA_URL = '/data/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'data')


EMAIL_BACKEND = env.str('EMAIL_BACKEND')
EMAIL_HOST = env.str('EMAIL_HOST')
EMAIL_PORT = env.int('EMAIL_PORT')
EMAIL_HOST_USER = env.str('EMAIL_HOST_USER')
EMAIL_HOST_PASSWORD = env.str('EMAIL_HOST_PASSWORD')
EMAIL_USE_TLS = env.bool('EMAIL_USE_TLS')

urls.py

urlpatterns+= static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
handler404 = 'generic.views.invalid_request'

Когда я установил DEBUG = True, тогда сервер может работать.Но когда я устанавливаю DEBUG = False, сервер выдает ошибку 500.

Какое решение ???
