Thread: skin edit

I have problems editing the default skin. There is no problem if i try to edit the main view, but i can not edit any of the sub-pages. For instance i can remove the header from the main view, but no way i can remove it from "pictures" subpage. It allows me to modify it, or even change the text, and the changes show up in dev. env. But when i restart it everything is back to default. Why is that, and how to change it?
(Sry for my bad english)
