I get to the very end of this part of the tutorial, reload the web page and load it, and receive this error:
DisallowedHost at /Invalid HTTP_HOST header: 'simonsterj.pythonanywhere.com'. You may need to add 'simonsterj.pythonanywhere.com' to ALLOWED_HOSTS.
I've used my own names for the databases/virtual environments so I've double/triple checked that I didn't make any mistakes when typing out paths.
I've also tried updating 'ALLOWED_HOSTS' in my local computer as suggested, pushed it to GitHub, and pulled it to the live server using the PythonAnywhere console. Still same error.
What could be the issue?
