I also followed this article but my ez doesn't work very well. I use two languages ("cat" [cat-ES, catalan version] and "es" [esl-ES, spanish version]), but it works like two different sites. I can log in (for example in the catalan), but when I change the language then i can't acces and i must log again! It works like two different websites with two different sessions!!!! How i can resolve this? I want to change between languages maintaining the same opened sesion!

Sorry about my poooor english! Thanks!!!
