Switch the interface language according to the accept-language request header
Compatible with DokuWiki
This plugin will automatically switch the DokuWiki interface language automatically for each visitor, depending on the sent Accept-Language header. It does not magically translate your content. It just changes the conf['lang'] setting based on the current user's preference.
Install the plugin using the Plugin Manager and the download URL above, which points to latest version of the plugin. Refer to Plugins on how to install plugins manually.
There's nothing to do except installing the plugin.
