I’m using TranslatePress to translate my site. It works by creating another directory on the top level of the domain, e.g. example.com/categories turns into example.com/en/categories. The problem is that the categories remain in their original sorting (since the “backend” category names are still the same, I guess), which leaves the categories in a strange order in the other language.
Unfortunately, there is currently no integration with this plugin, so it may not work correctly, you need to review this plugin in detail and customize it, according to the HivePress system.
