```bash
# Find process using port 8000
netstat -ano | findstr :8000  # Windows
lsof -i :8000                 # macOS/Linux

# Kill the process or use different port
python start_alwrity_backend.py --port 8001
```

**Database Connection Error**
```bash
# Reset database
rm backend/alwrity.db  # Linux/macOS
del backend\alwrity.db  # Windows

# Reinitialize
python -c "from services.database import initialize_database; initialize_database()"
```

**Missing Dependencies**
```bash
# Reinstall requirements
pip install -r requirements.txt --force-reinstall
```

#### Frontend Issues

**Port Already in Use**
```bash
# Use different port
npm start -- --port 3001
```

**Build Errors**
```bash
# Clear cache and reinstall
rm -rf node_modules package-lock.json
npm install
```

**API Connection Issues**
