We noticed our slider stopped working today and we think its because we haven't updated the theme.
Our problem is when the person who originally created our site using the theme they didn't use a child them. All the changes to the theme (backgrounds, widgets etc) have been made to the parent theme (although we haven't tampered with the css file directly. All changes have been done using the controls in the dashboard)
Is it possible to create a child theme with a site which has had the parent theme modified, do the update and not lose everything?
If not is there another way of updating without losing our content and layout.
