I'm having trouble with changing the url of a drupal localisation. All urls are clean, but contain a non-clean localisation part; ?q="language", e.g. ?q=de, ?q=fr. The site runs on nginx + mysql + php5.
I want to change this to either site.tld/"language"/page or to no url at all, e.g. site.tld/page.
How to change this in the rewrite rules?
