I can't figure out why Softaculous does not show my 'add-on' Domain. I've attempted to follow its instructions but notice the upper level, black panel, does not show a symbol for the addition. ( https://www.softaculous.com/docs/enduser/adding-domain/ ). Unfortunately, DA's online videos show an outdated interface and I can not find appropriate step-by-step instructions on how to make this work so I can get on with building my website.
