Please help...

I put the built pages in a /fr subdirectory, just below the root
(like www.site.com/fr)
When I follow the categories and subcategories by clicking, all is OK
(www.site.com/fr/categ1/index.html
www.site.com/fr/categ2/index.html....)

But when I try a Search, the results returned
forget the /fr/ subdirectory, being like:
www.site.com/categ1/index.html,
and of course don't exist at this path.

Did I forget a /fr instruction in some script ?

Thanks,

Patrick
