Hi Cayenne,

thanks for getting in touch about this. I just did some testing for another client and created some instructions. I think the setup is similar to what you are describing except it's based on GeoIP rather than browser language settings (I think that's what you are saying). So take a look at http://www.metamodpro.com/forums/topic?id=2387 for the basic instructions.

To alter it to detect browser language instead of GeoIP, you can use the Config tab to set "$language" to "Browser's preferred language". LEAVE THE "Preferred list of languages" BOX EMPTY FOR NOW (it has a very special use and you may want to use it later). Then in the Environment tab, type "fr" to detect French, and follow the rest of the instructions in the linked post.

If in doubt as to what Chameleon is doing, be sure to use Chameleon's Debug mode (in the Config panel from the main Rules list page). Then when you view the front end you should see debug output appearing describing which rules have been tried and which ones succeeded or failed.

I hope that helps, let me know if you still have trouble with it.
Best regards,
Stephen
