DISCLAIMER

By using this script, you take full responsibility for your web security. While we have done our best to secure it, we provide no guarantee, and we won’t be held liable for any loss or damage.

We do not guarantee that the scripts are unhackable. Your cybersecurity is your own responsibility.

These scripts are provided for educational and research purposes only. We do not support illegal or unethical use. Use at your own risk.

SECURITY

Enable 2FA (two-factor authentication) on your server/cPanel for enhanced security. If a hacker gains access to your server, they can compromise your entire system and database.

Be cautious with wallet addresses and payment gateways (if any). We recommend creating a separate user account to monitor and audit what users see on their end.

BACKUP

Before editing any code, always take a full backup of both your files and database. This will help you revert in case of errors.

Use hosting services that offer daily/weekly automatic backups so you can restore your site easily if needed.

DOMAIN NAME

When buying a domain name, avoid names similar to popular or existing domains to prevent confusion or being flagged as deceptive.
