Unable to migrate, django.db.migrations.exceptions.MigrationSchemaMissing - django

Question

I have no valuable data in my database and was unable to migrate, as you can see here:
ResetDjango postgresql database? flush does not work
I tried to reset the database using:
Delete migration files
Enter psql command prompt. Connect to database. drop schema public cascade; create schema public;
Step 2 unfortunately seemed to have removed my user role and rights so I went back to the psql command promt and recreated those.
Now I have tried to migrate again, and it still doesn't work. What might be wrong now?

Adding these two lines in settings.py at the top are important for mysql to connect:
from django.db.backends.mysql.base import DatabaseWrapper
DatabaseWrapper.data_types['DateTimeField']='datetime'
