Well, one major problem I see is that if Sentora installed properly, you should never see the Ubuntu ready page.
Did you already have apache or any other web server programs installed on the server before installing Sentora? If so, and you would like to continue to use Sentora, You will need to completely backup your sites and databases to your computer, install a fresh minimal OS with NO server programs (Apache, php, mysql, postfix, proftpd, bind, etc.) and completely reinstall Sentora. Then recreate your sites. (You may be able to do a Sentora DB backup also and try a restore of those databases also, but may be more of a headache.)
Also, you need to decide whether you want to use Sentora's DNS (preferred method) or DO's DNS. You can't use both.
