I'm using Twenty Ten 1.5. Tried making a child theme following book & codex directions. I intended to change nothing - was just doing it to avoid doing permanent damage to Twenty Ten when I start trying to modify things.
I did live preview, but instead of that lovely menu bar across the front, now there's just a list of menus.(it also lost my header image, but that should be easy to put back) So I panicked and cancelled.
How can I have a child theme but keep the menu bar?
