Hi, could you add localeLocale Locale = language version, often a combination of a language code and a region code, for instance es_MX denotes Spanish as it’s used in Mexico. A list of all locales supported by WordPress in https://make.wordpress.org/polyglots/teams/ en_SG? Could you add it? My client found that is missing – we need to print it correctly in the page headerHeader The header of your site is typically the first thing people will experience. The masthead or header art located across the top of your page is part of the look and feel of your website. It can influence a visitor’s opinion about your content and you/ your organization’s brand. It may also look different on different screen sizes..

Thanks a lot!

P.S. I’m a Czech developer, I can’t maintain or organize language team for Singapore English, just need a correct dropdown in the menu.
