Stock by Attribute v4.0 addon for v1.3.5-1.3.9

[mc12345678]

Where do I need to add that definition?

In ZC 1.5.5 it is found in: includes/languages/english.php (or in your template override of the english.php language)

The define is:

define('WARNING_PRODUCT_QUANTITY_ADJUSTED',##'Quantity##has##been##adjusted##to##what##is##in##stock.##');
