Нужна помощь после обновления Django

Question

Я обновил Django 2.2.5 до 2.2.6, и теперь я получил ошибку:

  Message=Failed lookup for key [title] in [{'True': True, 'False': False, 'None': None}, {'csrf_token': <SimpleLazyObject: <function csrf.<locals>._get_val at 0x0000023044F223A8>>, 'request': <WSGIRequest: GET '/'>, 'user': <SimpleLazyObject: <function AuthenticationMiddleware.process_request.<locals>.<lambda> at 0x0000023044E74D38>>, 'perms': <django.contrib.auth.context_processors.PermWrapper object at 0x0000023045017688>, 'messages': <django.contrib.messages.storage.fallback.FallbackStorage object at 0x0000023044F3A388>, 'DEFAULT_MESSAGE_LEVELS': {'DEBUG': 10, 'INFO': 20, 'SUCCESS': 25, 'WARNING': 30, 'ERROR': 40}}, {}, {'form': <AuthenticationForm bound=False, valid=Unknown, fields=(username;password)>, 'view': <django.contrib.auth.views.LoginView object at 0x0000023044F3AC08>, 'next': '', 'site': <django.contrib.sites.requests.RequestSite object at 0x0000023044F65088>, 'site_name': 'localhost:65093', 'LANGUAGE_CODE': 'da-dk', 'LANGUAGE_BIDI': False}, {'block': <Block Node: title.

В этом файле:

{% extends "admin/base.html" %}

{% block title %}{{ title }} | {{ site_title|default:_('Django site admin') }}{% endblock %}

{% block branding %}
<h1 id="site-name"><a href="{% url 'admin:index' %}">{{ site_header|default:_('Django administration') }}</a></h1>
{% endblock %}

{% block nav-global %}{% endblock %}

И если я нажму продолжить, также внекоторые другие файлы, большинство из которых отмечает разделы блока кода. Приложения работают нормально, но {{date}} также больше не отображается.

Изображение, где печатается год индекс после входа в систему

Изображение после загрузки другого модуля После загрузки другого модуля

Находится в макете и должен всегда отображаться.
