I enjoy the book very much, thank you.
I followed the instructions for building a child theme, but when I tried to install it, wordpress annaonced that "The package could not be installed. The theme is missing the style.css stylesheet". and that the Theme install failed.
I looked on the web and found this tutorial( http://op111.net/53/
) that says that after writing the style.css (which I did following the instructions in the book, I should upload my style.css to the same directory where the mother theme is, —wp-content/themes— and to make a new directory and name it “kid” I'm puzzled, is it posibble that a step is missing in the book?
