error La propiedad% s no es multilínea

Mi aplicación está recibiendo un error debido a la%s (Al menos, esto es lo que pienso), pero no sé por qué. He cambiado al código django para intentar obtener datos en la plantilla html. La plantilla se está cargando pero los datos no se están importando. La aplicación se ejecuta localmente pero la plantilla no está cargando datos y en el servidor me aparece este error:
