I'm a newbie just starting to use WordPress 2.0 and I'm very happy with it.
However, every time when I try to change Themes, I get the message saying that the installation is done but the new Theme lacks CSS sheets and therefore it can't be put in place.
I wonder if it's some security setup in my computer that's blocking it, or something else - I don't think it's the themes themselves as I've tried many different themes and get the same response.
Could someone shed some lights for me please?
Many thanks in advance.
