@muhammadtaqi @Mcnass Both of you please test the master branch and report back here. I’m waiting to cut a release to PyPI until I know that it works.

Also @Mcnass - dude, I can’t fix things in an hour, relax a little bit! 😆

I am running python -Wa manage.py check on a Django 1.11 project and this message appears.

But it will work with Django > 2.

if DJANGO_VERSION < 2:
    from django.contrib.gis.db.models import GeoManager
else:
    from django.db.models import Manager as GeoManager
