Could you kindly specify what kind of text you wanted to translate and what words were not translated.

Hello : some strings are translated, other are not. Below an example in admin section : http://i.imgur.com/x2k3isq.png

And here : on public side : http://i.imgur.com/Ge8CXIa.png

It looks like the localization script does not translate everywhere.
Maybe you could give us a list of files where the language strings are stocked ?

Thank you in advance
