I had the same problem, and this is what wordpress says in the manage themes area:-
The following themes are installed but incomplete. Themes must have a stylesheet and a template.
evolve Stylesheet is missing.
I have managed to upload the theme using filezilla through the binary transfer setting you mentioned earlier in the post.
I am now however getting an update notification through wordpress that I need to update the theme from version 1.0.0 to 2.9.2 – is this picking up the evolve lite theme from wordpress.org? I don’t want to update it if it is wrong to do so. Could you please advise.
