tzyganu, again thanks to care about my issue.
I tried the first solution and it is find until the point that some off header bar tabs is still pointing to original classic (f002) skin “as the home tab” wile other tabs point me correctly to the language one, that was created as you told me. I didn’t have that problem with the original Magento theme and blue skyn. I thing some thing is going wrong with the header nav bar off classic theme.
I will work on the second issue tomorrow .
By the way can you save me time telling me were are the .phtml and translate.csv files?
Thanks a lot!
