Django - No such table: main.auth_user__old

I was following the first app tutorial from the official Django docs and got this error when trying to save some changes made through the admin page. I did some research on it, but the possible solutions I was able to find, such as migrating the db, simply won't work. Just let me know if you want to see some specific part of my code.

Following is error:

OperationalError at /admin/polls/question/1/change/ no such table: main.auth_user__old Request Method: POST Request URL: http://127.0.0.1:8000/admin/polls/question/1/change/ Django Version: 2.1.4 Exception Type: OperationalError Exception Value: no such table: main.auth_user__old Exception Location: /Users/gfioravante/Projects/test_app/ta_env/lib/python3.7/site-packages/django/db/backends/sqlite3/base.py in execute, line 296 Python Executable: /Users/gfioravante/Projects/test_app/ta_env/bin/python3 Python Version: 3.7.1 Python Path:

and the traceback:

I just came across this myself, it looks to be related to https://code.djangoproject.com/ticket/29182. For now, you can just downgrade your version of sqlite to a version prior to 2.6 (e.g. 2.5.1)
