I have a WP MU deploy. I'm using many subsites, all with the same base domain and diferent directories:
http://www.prueba.com/ar (for Argentina)
http://www.prueba.com/uy (for Uruguay)
http://www.prueba.com/cl (for Chile)
I want to set up a diferent subdomain for Brazil as:
http://www.prova.com (for Brazil)
Since Brazil's language is Portuguese and Spanish "prueba" = Portuguese "prova"
It's working, the only problem is it doesn't work with the permalink configuration called Post name "http://www.prueba.com/ar/sample-post/" (more friendly) BUT only with the Default configuration "http://www.prova.com//?p=123"
I can't figure out how to make it work with the special Portuguese domain AND post name permalinks.
