🐛 Troubleshooting

Backend Issues

Port Already in Use

# Kill process on port 5001
lsof -i :5001
kill -9 <PID>

MySQL Connection Failed

# Verify MySQL is running
mysql -u root -p'Welcomenav1#' -e "SELECT 1"

# Check database exists
mysql -u root -p'Welcomenav1#' -e "SHOW DATABASES;"

Database Not Found

# Import database schema
mysql -u root -p'Welcomenav1#' < backend/menu_database.sql

Frontend Issues

Port 3000 Already in Use

# Kill process on port 3000
lsof -i :3000
kill -9 <PID>

Cannot Connect to Backend

Verify backend is running on port 5001
Check .env.local has correct NEXT_PUBLIC_API_URL
Check browser console for CORS errors

Dependencies Issues
