When trying to create a new style as the child of a parent style, I get this message: Tools Error A server error occurred. Please try again later. The new child style name appears under the parent style, but there's no cache-and-template-building phase, it just goes straight to the error message instantly. I haven't had any problem with this until now and I've probably created about a dozen child styles. I tried to do this with two different styles just to be sure it wasn't something about the parent style.
