I have created a child theme to edit some .php files. All the files in the root folder
/themes/shapely-child/ are loaded correctly.
However, I made a small modification to the
/themes/shapely/inc/extras.php file and placed this in
/shapely-child/inc/, but this file is never used. I also tried to place the file in the child theme root directory, but the parent file is always used. How can I get the child theme file to override the parent theme file?
