Apologies if this has arisen before, but I can't think of any keywords that don't return thousands of hits under search.
My site is http://www.therazor.org
It's a 3 col site that I want to change the theme on.
Under the Admin - Presentation - Available Themes, whichever theme I select doesn't have any effect: the original stays.
Do I have to manually copy the index.php from the theme in the theme directory to the root?
