TypeError at /admin/newsletter/submission/ argument of type 'NoneType' is not iterable #355

Closed rupertbaker closed 3 years ago

rupertbaker commented 3 years ago

Followed the steps in the docs and I'm able to create a Newsletter via the admin but I'm then unable to create a subscription (or a message and a submission).

Here is the traceback. Looks like something to do with timezone? Which I do have in settings: TIME_ZONE = "UTC" USE_I18N = True USE_L10N = True USE_TZ = True
