404 Error Page is a free Joomla system plugin that displays a custom 404 error page within your site’s design. The page content comes from a selected menu item, such as an article explaining the error and offering useful links or navigation suggestions.


When a visitor requests a missing page, the plugin preserves the original browser URL and returns HTTP status 404. Visitors see your prepared content without being redirected to another address.

Key features:

  • Select a default 404 error page.
  • Assign separate pages to published site languages.
  • Use the default page when a suitable language-specific page is not configured or is unavailable.
  • Display the page within the site template using the selected menu item’s settings.
  • Handle routing errors and 404 errors raised during component execution.
  • Preserve the original missing path when switching languages.
  • Configure language-specific pages without requiring menu item associations.
  • Prevent error-response caching.
  • Remove Canonical links from the 404 error page.
  • Preserve the priority of redirects prepared by Joomla.

To configure the plugin, create and publish a menu item with the desired content, select it in the plugin settings, and enable the plugin. You can also assign separate menu items to individual site languages. If no pages are selected, Joomla retains its standard error handling.

The interface is available in English and Russian.

404 Error Page позволяет показывать собственную страницу ошибки 404 в шаблоне сайта Joomla. Выберите общую страницу и отдельные страницы для разных языков — плагин сохранит исходный адрес и HTTP-статус 404.

404 Error Page — бесплатный системный плагин Joomla для отображения пользовательской страницы ошибки 404 в оформлении сайта. Содержимое страницы определяется выбранным пунктом меню: например, это может быть материал с объяснением ошибки, полезными ссылками и подсказками для посетителя.

При обращении к несуществующей странице плагин сохраняет исходный адрес в браузере и возвращает HTTP-статус 404. Посетитель видит подготовленное содержимое без перенаправления на другой URL.

Основные возможности:

  • Выбор общей страницы ошибки 404.
  • Назначение отдельных страниц для опубликованных языков сайта.
  • Использование общей страницы, если подходящая языковая страница не настроена или недоступна.
  • Отображение страницы в шаблоне сайта с учётом настроек выбранного пункта меню.
  • Обработка ошибок маршрутизации и ошибок 404, возникающих при выполнении компонентов.
  • Сохранение исходного несуществующего пути при переключении языка.
  • Работа языковых страниц без обязательных ассоциаций пунктов меню.
  • Отключение кэширования ошибочного ответа.
  • Удаление Canonical со страницы ошибки 404.
  • Сохранение приоритета перенаправлений, подготовленных Joomla.

Для настройки создайте и опубликуйте пункт меню с нужным содержимым, выберите его в параметрах плагина и включите плагин. При необходимости назначьте отдельные пункты меню для языков сайта. Если страницы не выбраны, сохраняется стандартная обработка ошибок Joomla.

Интерфейс доступен на русском и английском языках.
