Django 2.0 TemplateDoesNotExist: grappelli:admin/base.html

[RecNes]

Order of INSTALLED_APPS:

'grappelli_extensions',
'grappelli',
'django.contrib.admin',
...

'APP_DIRS': True, available in TEMPLATES in settings.py

TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [ os.path.join(BASE_DIR, 'templates'), ], 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.template.context_processors.media', 'django.template.context_processors.static', 'django.template.context_processors.tz', 'django.contrib.messages.context_processors.messages', ] }, }, ]

I also tried to disabled 'APP_DIRS' and added the 'apptemplates.Loader' to 'loaders' in 'TEMPLATES' setting.

'loaders': [ 'apptemplates.Loader', ]

But no luck to use grappelli-extensions with Django 2
