Hi
I’ve started using your piwik pro plugin for wordpress to track sales. It works generally well.
Except I see that when a variable product is sold it records the parent product, and not the actual sold child product.
For instance:
Variable Product “sweater” sku 0
product variation “blue” sku1
product variation “yellow” sku2
where the variations are children of “sweater”.
The plugin records a sold yellow sweater as a sold sweater with sku 0.
There’s pretty good documentation for woo regarding simple products and variable products.
