Fix Django Blog Errors

I have a small Django blog project that suddenly stopped working after I moved it to a new environment.

What has to be done
• Pull the repo, reproduce the errors, and audit settings (INSTALLED_APPS, TEMPLATES, DATABASES, STATIC, etc.)
• Restore template discovery so every page renders without exceptions
• Resolve all migration issues and ensure `python manage.py migrate` completes on a clean database as well as an existing one
• Make sure the Django admin loads, authenticates, and behaves normally
• Start the application with `runserver` (or the provided WSGI/ASGI entry point) and confirm zero runtime errors
• Hand over a concise report outlining what was broken, what you changed, and any follow-up recommendations

Please describe the approach you intend to take to solve the problem in your proposal.
