I'm a reseller on a shared hosting cPanel instance running CloudLinux 6.10. I also have a shared reseller account on a CentOS 7.6 server running cPanel. On the CentOS server, I'm able to administer my primary cPanel account from WHM, and also when I log in to cPanel I can switch away from my primary account (to resold accounts) and then switch back to my primary account. On the CloudLinux machine, I can't do either. It seems the primary account is totally separate - it doesn't appear in WHM and I can't switch back to it when I switch away from it in cPanel. No idea if this is something to do with CloudLinux, or some other configuration. The server administrators have told me this is the way it should be, but can someone confirm? Thanks!
