I haven’t done any child theme, but I have been using theme options-layout-enter your custom css.
Suddenly when I was making just a little change, a huge part of my custom css disappeared. Whre is it located in the back-up. I really would like to find it!
Help soon!
Backups are handled by your hosting provider, not WordPress. If you don’t see a backup manager in your hosting control panel you’ll have to contact them.
