Marcus Christie commented on AIRAVATA-3333:
-------------------------------------------
from_json comes from django-modelcluster and is expected on Page subclasses,
but wouldn't be on Navbar, but it's weird that somehow (?) the
page.specific_class is Navbar?
> Wagtail: type object 'Navbar' has no attribute 'from_json'
