My script works in functions.php but not in your plugin

Thanks, It’s to add a sidebar to the WooCommerce product pages in the Web Savvy ‘Jessica’ theme.

// Remove forced full width layout for single products
remove_filter( 'genesis_site_layout', 'jessica_woo_product_layout' );
// Use alternate sidebar function
remove_action( 'get_header', 'wsm_child_sidebars_init', 15 );
add_action( 'get_header', 'wsm_alt_child_sidebars_init', 15 );
/**
 * Remove sidebars
 */
function wsm_alt_child_sidebars_init() {
	remove_action( 'genesis_sidebar', 'genesis_do_sidebar' );
	remove_action( 'genesis_sidebar_alt', 'genesis_do_sidebar_alt' );
	remove_action( 'genesis_sidebar', 'ss_do_sidebar' );
	remove_action( 'genesis_sidebar_alt', 'ss_do_sidebar_alt' );
	remove_action( 'genesis_sidebar', 'gencwooc_ss_do_sidebar' );
	remove_action( 'genesis_sidebar_alt', 'gencwooc_ss_do_sidebar_alt' );
	add_action( 'genesis_sidebar', 'jessica_alt_child_do_sidebar' );
}
function jessica_alt_child_do_sidebar() {
	if ( $id = jessica_child_has_ss_sidebar() ) {
		if ( dynamic_sidebar( $id ) ) { /* do nothing */ }
	}
	elseif ( class_exists( 'Woocommerce' ) ) {
			if( is_shop() || is_product_category() || is_product_tag() || is_product() ) {
				genesis_widget_area( 'store-sidebar');
			}
			elseif( is_archive() || is_single() || is_category() || is_page_template( 'page_blog.php' ) ) {
				genesis_widget_area( 'blog-sidebar');
			}
			else genesis_widget_area( 'page-sidebar');
	}
	elseif ( class_exists( 'IT_Exchange' ) ) {
			if( it_exchange_is_page() || is_tax( 'it_exchange_category') || is_tax()  ) {
				genesis_widget_area( 'store-sidebar');
			}
			elseif( is_archive() || is_single() || is_category() || is_page_template( 'page_blog.php' ) ) {
				genesis_widget_area( 'blog-sidebar');
			}
			else genesis_widget_area( 'page-sidebar');
	}
	elseif ( class_exists( 'WP_eCommerce' ) ) {
			if( wpsc_is_in_category() || wpsc_is_product() || wpsc_is_single_product()  || is_page( 'products-page') || is_tax() ) {
				genesis_widget_area( 'store-sidebar');

	}
	else {
		if( is_archive() || is_single() || is_category() || is_page_template( 'page_blog.php' ) ) {
			genesis_widget_area( 'blog-sidebar');
		}
		else genesis_widget_area( 'page-sidebar');
	}
}

Thanks Arthur, I understand entirely. I thought the problem might be very clear to you when you saw it, but no worries. I’ll go back to using functions.php.
