Hello, I have two questions and problems. I use K2 to make a portfolio on my website
1 - I have a problem to display the menu when I'm on the English version (univ.universelweb.fr/en/component/k2/item/64-nuit-du-hack-corero.html)
2 - How did your associated for two elements of different language like joomla menu links?
thank you for your help and sorry for my english :)

Hi. None of your issues have to do with K2 so i cannot help you. Try to make some search using Google to find resources about how you implement a multilanguage site in Joomla! 2.5.
