I duplicated the GP theme folder to a new folder called GP-Idylwood. I put this line at the top of the stylesheet.
Theme Name: Idylwood Custom
Theme URI: https://generatepress.com
Description: Custom Idylwood Child Theme
Author: Pixelita Designs
Author URI: https://pixelita.com
Template: generatepress
Version: 1.0.0
The functions.php file for the child theme is empty.
And the child theme appears and I can make *some* modifications to it. However a lot of the functionality (typography, layout, menus, etc.) is gone. And GeneratePress settings no longer appear under the Appearance section. The plugin is present and activated.
Also, on the site itself, the front end, there is the dread white screen of death.
What did I do wrong?
