Site Language: Install translations on the fly
|Reported by:||ocean90||Owned by:|
This was previously included in #15677, but we decided to extract it for now, because it needs some more work.
The new language dropdown shows in addition to the installed languages also all available translations. When you select one of the available translations core will download the language pack and switches the site language.
The main issue is the access to the filesystem: If it requires the credentials it currently does't work, because of the Automatic_Upgrader_Skin() in wp_download_language_pack().
