Rule 41

Value of end not valid rule for attributes or attribute parents


The error is caused because the item is a variation attribute (child) or has attributes (parent), and the availability was set to "Always Available - Disable when Unavailable." This can be caused because it was selected or because the the default for "Rule" is set to "End" in Settings > Selling > Store Options.

Variation listings may not have this availability Rule on the storefront. 

To fix: Change the Availability for the parent and the child items in the variation to "Inventory Controlled -  Always Display" - which will display variants as "Out of Stock" when they reach 0 Stock.

Note: This translates into Rule:Update instead of Rule:End in bulk
