Can't add products to discount/coupons after migrating from Joomla to Wordpress

-- HikaShop version -- : 6.6.0
-- Joomla version -- : 7.2.0 /Wordpress
-- PHP version -- : latest
-- Browser(s) name and version -- :  Firefox 156.0

I have successfully moved my whole hikashop from Joomla to Wordpress - overall, it went very smooth.
However, I have one issue:
In discounts/coupons, I can't select the products, they don't appear - I guess, there is something pointing in the wrong place?
Any idea how to fix this?
Thanks in advance!

solved! Thanks to Claude...

Hi,

Glad you got it working, and thanks for the report. It wasn't your migration: on WordPress, the product selector of the discount form (and the other selectors of the same kind in the backend) got its list of products back wrapped in a full admin page, so opening a category showed nothing. We reproduced it on a fresh WordPress install and fixed it. The fix is in the 6.6.0 package you can download now from your account, so reinstalling it over your current HikaShop is enough.

If you changed a HikaShop file to solve it, reinstalling the package will overwrite that change, which is fine since the fix is included. If you did something else, could you tell us what, so we can check that it's covered too?
