This Theme is a hack for multilingual blog using multisite wordpress. It redirect users from "/" to "/en/" or "/fr/" in function of the accepted languages of the browser. The Theme redirect the 404 error page too.
This theme is a quick and dirty hack for my multilingual blog (http://oncleben31.cc). I don't have any competency in Theme development. Don't hesitate to fork and improve it.
This theme is a good companion to Multisite Language Switcher (by lloc) plugin for Wordpress. I've develop a similar plugin few years ago but this one is far more mature. Give it a try
Install this theme on your network and use this theme for the root blog (which is useless).
- use theme option to set the languages and redirect adresses
- don't use only the prefered language ($Langue[0]), use the others.
- add an ignore list for (robot.txt or sitemap file generated by plugin or wordpress)
