not display tab description when empty

Hello,

Try this code to your child theme’s functions.php
In case you do not have child theme then add code using this plugin – https://wordpress.org/plugins/code-snippets/

// Remove Empty Tabs
add_filter( 'woocommerce_product_tabs', 'wcfm_woo_remove_empty_tabs', 20, 1 );

function wcfm_woo_remove_empty_tabs( $tabs ) {

	if ( ! empty( $tabs ) ) {
		foreach ( $tabs as $title => $tab ) {
			if ( empty( $tab['content'] ) && strtolower( $tab['title'] ) !== 'description' ) {
				unset( $tabs[ $title ] );
			}
		}
	}
	return $tabs;
}

Thanks.
