Used to be the best theme and now it has a major flaw. DO NOT UPGRADE THIS THEME! If you have a custom home page it replaces it with it's own "Hello World" page by overriding the WordPress home page by default.
The last thing a client wants to see is "Hello World" (when there is no such Post or Page) and the CyberChimps logo instead of their own content!!! On a company website this is a major disaster.
I had given this a 5 star rating before - since CyberChimps has bought it it is nothing but trouble - I now give it zero stars.
