Default cPanel Webpage
This error is caused due to there being no configuration file on your website. This can happen when you haven't created your new domain within cPanel, but your domain has Name Servers or DNS A Records pointing towards the server public IP address or you have recently terminated your Hosting Services. If you've recently terminated your services, please ensure you cancel your domain and/or point your nameservers to your new provider.
If you require more information, please contact OctaWeb.
