I try currently the template loader, and it seems not to work, isn't it?

The init hangs with a lock:

Traceback (most recent call last):

I faced the same issue (init hanging with a lock) today when testing djangocms-multisite. Did you progress any further on this @jedie @yakky ? Thanks.

[yakky]

@fedriz are you using the above feature of django-multisite?

(@yakky let me know if we are talking about the same thing)

I've never had this problem. Those are the loaders that I currently use, check if you are using the same settings.

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [
            os.path.join(BASE_DIR, 'configurator', 'templates'),
        ],
        'OPTIONS': {
            'context_processors': [
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
                'django.template.context_processors.i18n',
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.template.context_processors.media',
                'django.template.context_processors.csrf',
                'django.template.context_processors.tz',
                'sekizai.context_processors.sekizai',
                'django.template.context_processors.static',
                'cms.context_processors.cms_settings'
            ],
            'loaders': [
                'django.template.loaders.filesystem.Loader',
                'django.template.loaders.app_directories.Loader',
                'django.template.loaders.eggs.Loader',
                'multisite.template.loaders.filesystem.Loader',
                'django.template.loaders.app_directories.Loader',
            ],
        },
    },
