Troubleshooting

PHP Version Mismatch

Install the required version:

sudo apt install php7.4

Database Connection Issues

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

sudo systemctl status mariadb

Ensure that the database service is running.

Permission Issues

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

sudo chown -R www-data:www-data /var/www/html/DVWA

Access Issues

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