I used the “Child Theme Configurator” plugin, and created a child theme. I’ve been working in there, and decided I wanted to add a search bar right below the menu. From the back end I uploaded the sf-header.php file and tried to edit it, but no changes are happening. It seems that the parent theme files are overriding the child theme file that I uploaded. Is there a way to override the parent theme’s sf-header.php file so that I can make these changes through the child theme?
