Hello!
Just a happy announcement that InterWorx is, once again, fully supporting CloudLinux for EL7 servers. 
There is a brand new plugin available–you can find installation and usage information here: https://www.interworx.com/support/faq/install-use-cloudlinux-plugin-interworx/
If you have any questions, let me know!
