This article applies to websites hosted on our newer https://cp.blacknighthosting.com platform
It isn't possible to get plesk on our cp.blacknight.com hosting plans
If you have a cloud VM or dedicated server you can access plesk at https://your-server-IP-or-hostname:8443
In order to fully manage your hosting plan you need to log in to the Plesk panel itself. You are limited in the actions you can take in cp.blacknighthosting.com itself.
Log in to https://cp.blacknighthosting.com and go to your Plesk control panel:
Sevices > My Services > Click on your Plesk plan (not on the domain name itself) > Plesk
