Can you update the line from models.py:
from wagtail.utils import camelcase_to_underscore to wagtail.coreutils import camelcase_to_underscore

also in views/unsubscribe.py
You can add the wagtail version logic ... i.e. for version 5, change line from wagtail.core.models import Site to from wagtail.models import Site
