I have one page witch has a different language then the rest of the site.
I looked in to many plugins but I can't find a way to chance the content language
<html lang="nl-NL" prefix="og: http://ogp.me/ns#"> for just one page.
I use Yoast SEO and he uses
<meta property='og:locale' content='nl_NL'/> and that also needs to be en_us
