Hello forum,
my question is about Switcher Language block (Drupal 6.10)
I have activated this block (2 languages: Spanish & Valenciano). It works perfectly in all website except from the home page (home page=node type page, menus and blocks don't switch language). Only works wrong from home page, from other nodes works OK.
Somebody knows what happens?
Thank you!
Fanny
