Alright, I got it fully working now.
I had to use this in the conf files:
WSGIDaemonProcess flaskapp
python-home=/home/bfxqsxmy/public_html/flask/venv/
python-path=/home/bfxqsxmy/public_html/flask/
WSGIScriptAlias /app /home/bfxqsxmy/public_html/flask/application.wsgi
process-group=flaskapp application-group=%{GLOBAL}
And then this in the application.wsgi file
from pfm.test1 import app as application
Now I can try migrating the actual app over, including the .env file, and
seeing if it works.
