I'm using Joomfish 2.0 beta with the language selector (swedish and English)... According to what I have read the Joomfish - Basic Router plug-in should be disabled and the System - ARTIO JoomSEF plug-in should be enabled instead. This works good in most cases! But not in same cases: I have a swedish translation for Community Builder profile and Fireboard that worked before disabling the Joomfish - Basic Router. Now both the Community Builder profile and Fireboard is in english nomatter which language I choose...
This problem is caused by some incompatibility of our JoomSEF plugin with language settings for components running in legacy mode. This will be fixed in next release.
