WordPress plugin which redirects from the root site of a multisite project to a language specific network site.

Please Note: This plugin doesn't allow content on the root site! Please read this description carefully to see if this works for you.

The decision which language should be used is based in the browser language of the user which is usually sent as 'Accept-Language' header (PHP: $_SERVER['HTTP_ACCEPT_LANGUAGE']).

The plugin provides a configuration page where supported languages, redirect targets and the default language can be configured.

The plugin should be activated only on the root site. It shouldn't be active on the language specific network site.

The plugin is developed on Github. Feel free to fork the project or create pull requests.

This plugin was originally developed for monkkee and is inspired by oncleben31.cc
