Background of the issue:
I am trying to maintain the default variation selection for WooCommerce products translated from Italian to English using WPML. The issue started a few weeks ago, possibly after an update. My products are originally in Italian and translated into English. Each product has 4 variations with a default one selected. I want the English versions to have the same default variation as the Italian products. Here is a link to a page where the issue can be seen: hidden link. I expect the English page to display like the Italian page: hidden link.
Symptoms:
English products no longer have a default variation selected. Customers must manually select a variation to see further pictures and add the product to the cart. In the backend, the Italian version shows a default variation, but the English version shows 'Default Form Values: No default' and this value is locked.
Questions:
How can I ensure that the English versions of my products have the same default variation selected as the Italian versions?
Is there a way to fix this issue without manually editing 1500+ products?
Sure please, go ahead with duplicating the website. I cannot create a staging site as the website is too big and I don't have the space for a copy on the server.
(Please let me know as soon as you're done with the duplication and I can delete the plugin, as my server reached 95% of its capacity and it's triggering some errors)
Thanks, now the space on the server came back to normal.
I don't see the solution applied to hidden link: when I open the page after a hard refresh there's no variation pre-selected (see in my screenshot the button "add to cart" disabled).
In the backend hidden link > Variation the "default form value" is indeed empty and locked.
Actually with the modification done the Description field of 3 non-stardard variations had been deleted; I had to put it back as just one variation needs to stay visible in the front-end. (Anyway, the issue doesn't have much to do with that, I just want the standard variation to be pre-selected).
As for other products where the issue occurs, for example: hidden link hidden link hidden link hidden link
However, before the issue used to be in all products and now in half of them or a bit less. Could it be something you've done?
