If you have selected an OS template with McMyAdmin server control panel for your VPS, make sure to wait at least 5 minutes so it would finish installing.
Afterward, you can connect to your McMyAdmin panel by writing your server IP address into the browser. Your VPS IP can be found in Server management area.
For example, http://127.0.0.1:8080 where 127.0.0.1 will be replaced with your server IP address.
To log in enter username "admin" and your VPS password. If you don't remember your password, you can change it in your Server management area.
