I deleted a product, accidentally hit the back button and it appears Zen is not setup for such an instance:

[21-Mar-2018 01:58:01 UTC] Request URI: /admin/product.php?cPath=4&product_type=1&pID=34&action=delete_product

[21-Mar-2018 01:58:01 UTC] PHP Warning: Creating default object from empty value in /home/public_html/mysite.com/admin/product.php on line 326

There were no problems with the product being deleted or any on screen errors this was quietly hiding in the /logs folder.
