 * Hi [@ron441241](https://wordpress.org/support/users/ron441241/) ,
 * We recommend deactivating and completely deleting the Print Invoice & Delivery
   Notes plugin, then reinstalling the latest version to ensure all required files
   are properly restored. This will not affect your existing orders.
 * If the issue still persists after reinstalling, please share a screenshot of 
   the red error box and your WooCommerce System Status report so we can investigate
   further.
 * Best regards,
   Anjitha
