can these fields be reversed?

Hi Impex,

Thanks for reaching to us and take our apologies for the long delay in answering.

Use the below code for reordering the tabs, just set priority values per your needs. Paste the code into the functions.php file in your Child theme.

/**
 * Reorder product data tabs
 */
add_filter( 'woocommerce_product_tabs', 'woo_reorder_tabs', 98 );
function woo_reorder_tabs( $tabs ) {

	$tabs['reviews']['priority'] = 5;			// Reviews first
	$tabs['description']['priority'] = 10;			// Description second
	$tabs['additional_information']['priority'] = 15;	// Additional information third

	// Custom Tabs are from Product Settings
	// $tabs['wd_custom_tab']['priority'] = 2; 
	// $tabs['wd_custom_tab_2']['priority'] = 3;

	// Additional Tabs are from Theme Settings
	// $tabs['wd_additional_tab']['priority'] = 4;
	// $tabs['wd_additional_tab_2']['priority'] = 5;

	return $tabs;
}

Hi Impex,

1. Order tabs

I switched to Child theme and re-add code, please check again.

2. Widgets

Try to install Classic Widgets plugin to fix this problem https://wordpress.org/plugins/classic-widgets/
