Oh! yeah sure, you can describe it step by step, and let know what error you got (or don’t) Just to be sure: you use multisite option for a multilinguistic website, right?
for the URL scheme in it.domain.tld or en.domain.tld it would require 2 different wordpress install (from what i learned by delving down the forum) and that’s how yunohost deals with domains. and its exactly as you said your designer would perform a double effort for both.
i saw a post about “too many redirect” error when using multisite plugin on the forum. It lead me on github and apparently you have to disable and re-enable the extension as said here. I don’t know if they talking about multisite or the extension they talked about in the post.
then its something really new or never adressed on the forum then. As i dont use wordpress and cant even really try (really limited hardware) you should ask on the forum, because if i ask on your behalf they’ll ask me logs and all that jazz
