Django view not rendering - sidebar & header загружаются нормально, но основное содержимое не загружается

Я прошла через столько разных вещей и просто не могу разобраться в этом; нужен свежий взгляд хаха

Мой вид не отображается, и, похоже, это происходит во всех моих приложениях и целевой странице - боковая панель и заголовок загружаются нормально, нижний колонтитул загружается частично, но я считаю, что это связано с тем, что основной контент не загружается.

Снимок экрана текущей HTML страницы - не рендеринг вида
