I hope I'm not asking a dumb question here, but let's say my WordPress skill is somewhere between beginner and intermediate (I normally code straight HTML sites), so it would be really awesome if someone would carefully explain my options. So I'm helping a relative set up a website on WordPress (premium theme, customized, own content), but the thing is it needs to be in two languages with, essentially, two separate versions of the site (so no automatic translation plugins). Also, when it will be under development, the main page for the domain needs to show a plain HTML "Coming Soon" page (already coded, but just I mean the main directory can't show WordPress).
Whether we put one language on the main domain or put them both on subdomains or both in subdirectories doesn't really matter, but when someone goes to the main domain, they will need to see the main language version as default. I am also fine with adding custom code to the headline that can switch the user between sites.
So anyway, I'm wondering if I should use multisite? I've never done anything with that before. I guess the reason I am considering this is because I want to first make the site in one language, and then easily copy the whole thing into another WordPress site for translation. So would it let me, for example, make a WordPress site in one subdirectory or subdomain, and then clone that site to a different subdirectory or a different subdomain (or even the parent domain)? I heard of NS Cloner but I don't really have any experience with that or know what to expect.
I believe my other option, not using multisite, would be to use the Export tool on the first (regular) WordPress installation, and then make a new installation on the other subdirectory, and import that. But would that automatically include all the settings and photos and pages? Would that require that I first install the custom theme I used for the first site, or does that get included in the export/import process?
P.S. This is my first post here, so Hi everyone!
