So I have a WordPress multisite install with over 20 sites. For some reason, two of them are using aliases in cPanel, even though they're not redirecting to anything, and they don't have other domains associated with them.
That is: blueeyes.seventh-star.net and sailormoon.seventh-star.net
But I have a ton of other WordPress sites on the same install: atw.seventh-star.net, for example. But these don't show up as aliases in my cPanel, and I'm trying to figure out why JUST those two would need it. I only have a limited number of aliases, so I don't want to use them if I don't have to.
I tried deleting the blueeyes.seventh-star.net ALIAS in cPanel (nothing in WordPress, nor anything anywhere else) and it broke the whole thing-- the site became inaccessible!
I have the Domain Mapping plugin, Multi-Domains for Multisite, but I'm not sure if they interfere with one another or anything else. The other thing I can think of is Contact Form 7, since I know that having an email address that matches the domain of the website is important for validation, and in order to add a "fake" email address (e.g. email@example.com) to the settings, perhaps that's why an alias exists...?
