Вызов функции-члена - null

Question

Когда я пытаюсь получить доступ к своему приложению, я получаю эту ошибку - Неустранимая ошибка: вызов функции-члена home() on null в /home/evilsro1/domains/evils.ro/public_html/forum/admin/applications_addon/other/groupjoin/modules_public/view/view.php в строке 140

Я использую IPB3.4.9, и имя приложения Applications Systems v2.3.0.1

Код PHP:
