I think I grasp childthemes, and have used them to make changes. My issue now is that I restored everything back to normal, and still have my child theme directing to my parent theme but I removed all custom styling that I had added. But, just having that child theme activated makes my site's functionality go whacky. Nested pages don't show up, etc. Is it possible that my free theme (ArtWorksResponsive)has a way to block a child theme?
My child theme style.css looks like this:
Theme Name: Jordan
Description: This is a child theme to Jordan's Artworks site.
It is essentially blank, but it messes up the site. Any ideas?
