Q: Django ModuleNotFoundError: No module named 'core' I was working on a blog. The static files are in a bucket on aws and the website is being hosted on heroku. Each time i try to edit a blog post ie(http://127.0.0.1:8000/admin/blog/post/1/change/) I keep getting this error:
  File "C:\Users\Hp\AppData\Local\Programs\Python\Python310\lib\importlib\__init__.py", line 126, in import_module
    return _bootstrap._gcd_import(name[level:], package, level)
