Hi Willem-Siebe,
a lot of this new feature, which was not announced in a special post, was discussed in this ticket: https://core.trac.wordpress.org/ticket/28303
Basically starting with 4.3 you can choose and download “language variants” such as “German formal” or “Portuguese formal” without loosing this variant on an autoupdate. Before 4.3 the language variants would have benn overwritten by the “default” variant.
Another issue with a language variant is the fact, that most plugins and themes don’t provide translation files for those variants. As WordPress core has no fallback strategy, it would choose English, which is probably not what a user which has choosen a variant wants. This it what the plugin tries to fix.
Hi, thanks for the link. That helped me a lot.
One thing I don’t understand, I updated my website to 4.4.2. However, in the list of languages I don’t see the Dutch ‘Formal’ variant. But here you see it should be available: https://translate.wordpress.org/projects/wp/4.4.x
Why is it not visisble to me? I know it’s not related to your plugin, but hope you can clarify.
I do see that the Dutch Formal language is available for my en_US wordpress installs, but not on my nl_NL installs, why is that making a difference?
Do you see any other language you can install? If not, this could be due to a file permission issue. That your are not able to install any new language.
You can always upload the po/mo files manually using FTP to your site. They usually go into the wp-content/languages folder.
Yes, I see lot’s of languages, for example also the German Sie version. Strange, but I’ve also posted a forum message in Dutch WP forum, because I can’t understand why it makes a difference that back then I installed it as nl_NL or en_US…
It’s solved by pressing the update languages button in WP backend.
