Unlike other tranlation plugins, MultilingualPress uses WordPress Multisite, so you can use it to connect your multi-sites in different languages and at different versions, such as yourdomain.com, yourdomain.fr and yourdomain.de.
You can use it to connect numerous websites. All you have to do is set the default language for each of your sites. Users can use their own native language with gadgets or links added to each post.
Although every website in the Family is completely independent, MultilingualPress edits all articles on one page. At the same time, you can add any translated articles without having to switch websites, thus speeding up translation and simplifying the translation process.
Another advantage of MultilingualPress is that it connects versions of your site’s translations to ensure that they are linked to each other. When the plugin is disabled, these translated versions will continue to exist, the same as when the plugin is enabled.
