Polyglott_XH offers advanced features for multilingual CMSimple_XH websites. The main point is that it allows to mark individual pages of different languages as actual translations, so visitors as well as the admin can quickly switch between the translations of a certain page.
Furthermore the plugin automatically emits information mainly for search engines regarding available translations of the current page (so called hreflang links).
The plugin requires CMSimple_XH ≥ 1.5.6 and PHP ≥ 5.0.0. It is released under GPLv3.
Polyglott_XH couldn't be tested so far in various environments. It is a so called beta version. Use with caution!
