Hi @johndcoy,
Thank you for your help…
I’ve just found out something new:
– I export products from “Wines” category
– I edit the CSV file to replace “Wines” with “Wines, Wines > Other wines”
– I import my CSV and update products with same id
Then, I go to my webshop and click on “Wine”. On the category archive page, I can see “Other wines (515)”, but when I click to watch this subcategory, there is nothing to display until I edit thoses products with WP.
This make me suppose that the problem is not related to my API query (everything looks fine). Maybe it is because I cannot set one category as the Main one… What do you think ? I noticed the “Main” category is related to Yoast seo plugin.
