<priority>0.8</priority>
</url>
</urlset>- Use HTTPS - Required for Stripe, passwords, etc.
- Validate on Server - Never trust client-side validation alone
- Rate Limiting - Prevent brute force on login forms
- Password Requirements - Already enforced (8+ chars, mixed types)
- CORS Policy - Restrict API access to your domain
- Environment Variables - Never commit API keys to Git
Solution: Ensure all CSS files are in the same directory as HTML files.
Solution:
- Check API key is correct
- Check browser console for errors
- Verify HTTPS (Stripe requires secure connection)
Solution: Ensure script.js is loaded at the bottom of HTML file.
Solution: Check browser console. Update form action URLs to your backend.
