I’m sorry for posting first. I found the cause of my problem. The problem was that I imported the parent theme style sheet into my child theme style sheet instead of using wp_enqueue_style.
Here is my solution.
In the child theme directory add a functions.php file with the following code:
<?php
function my_theme_enqueue_styles() {
$parent_style = ‘business-idea-style’;
wp_enqueue_style( $parent_style, get_template_directory_uri() . ‘/style.css’ );
wp_enqueue_style( ‘child-style’,
get_stylesheet_directory_uri() . ‘/style.css’,
array( $parent_style ),
wp_get_theme()->get(‘Version’)
);
}
add_action( ‘wp_enqueue_scripts’, ‘my_theme_enqueue_styles’ );
?>
