Troubleshooting

1. PHP Version Mismatch

   • Install the required version:

     bash
     
     sudo apt install php7.4
2. Database Connection Issues

   • Verify database credentials in config.inc.php and check service status:

     bash
     
     sudo systemctl status mariadb

   • Ensure that the database service is running.

3. Permission Issues

   • Ensure /var/www/html/DVWA is owned by www-data:

     bash
     
     sudo chown -R www-data:www-data /var/www/html/DVWA
4. Access Issues

   • If you follow the exact steps in chapter 2, please make sure HTTP is selected when configuring the Origin at SwiftFederation Portal.

   • If you're installing DVWA on a cloud instance (e.g., aws EC2), ensure that the instance's inbound rules are correctly configured to allow public internet traffic on ports 80 and 443.

     

   • SSL certificate generation may take a few moments. Please navigate to Websites > your domain > Config > SSL to verify that the certificate has been issued. Once confirmed, try accessing your DVWA site again.
