[SOLVED] The current theme is not customizable

After I copied a style, the copy is still not customizable.
I have this problem with two different sites.
Any proposal?

Yes youre right and you can not copy the theme style with Joomla admin.
If you want to have different styles for different menu items you have to use the template feature: "profiles"
>> Template Options > layout > copy

Problem solved.
