I've been searching the internet for the last hour but I can't find anything up-to-date to do this (all the suggestions are about plugins that haven't been updated in ages, see this questionthis question).
Is there any way to specify a different back-end language for different users? I like my WP back-end to be in English but all my coworkers prefer it in their own language (Italian), is there any way to live in peace with them?
Props if your method doesn't rely on URLs (/?lang=it and such) and isn't a plugin, but a functions.php function.
Thanks, have a great new year!
