[support] Front page with i18n sometimes not working

[Marolijo]

Hello, on the site http://plats.polnetwork.biz I use i18n, so i have
http://plats.polnetwork.biz/ca
and
http://plats.polnetwork.biz/es

The front page is /inici on both cases, and the default language is
/ca but from some machines the front (inici) is not working and
appears an error "The required page could not be found"

Any idea?

Thank's for all
Pol
