Hi Prekki,

I've just done a quick test of this to check it, and so far my test seems to be working fine on J3.2:

1 - duplicated Protostar and called it Protostarnew
2 - edited the Protostarnew template's index.php file to include the word "PROTOSTARNEW" so I can track it easily
3 - made a Chameleon rule with no conditions, and in the Succeed action I set the protostarnew template style
4 - viewed a page.

Result: I see PROTOSTARNEW appear as it should.

So fundamentally I think it works, but obviously not in your case

I think that the duplication process may depend a bit on the way the template (the one you are duplicating) is constructed. If it uses any links in it that contain the hard coded name of the template, then those links will refer to the original template instead of the duplicated copy.

Could that be the problem?

Cheers,
Stephen
