After Installing Cloudlinux on Direct admin users complain to face this error which says
User admin was not setup to use LVE Manager yet Please, run as root: '/usr/bin/da_add_admin admin' to enable 'admin' to manage CloudLinux settings.
This error can be fixed easily with the help of following command:
/usr/bin/da-addsudoer admin add_user
Once you hit this command the error should have faded.
