I'm trying to create a child theme using Oxygen. When I create the files and refresh my web page, the navigation header bar underneath the header completely disappears. If I return to the parent theme, it's back. But, the css and rtl files are essentially empty other than the import function. Does anyone know what might be causing this?
Note: please respond using layman's terms. I'm not an experienced coder.
The blog I need help with is artisancos.wordpress.com.
