I wasn't able to produce a minimal example of what was going on, but it is fixed now. Essentially, I did the following:
1. Upgraded to Django 1.8.6 . 2. Ran python manage.py collectstatic (as suggested in https://community.webfaction.com/questions/18544/there-is-not-popup-window-for-one-to-many-relationship-with-djangos-admin-v18 ) I hope this is useful to someone else. -- You received this message because you are subscribed to the Google Groups "Django users" group.
