{/code}Hey, I added a code to functions.php on my child theme and I can't manage to translate it.
I attached a screenshot. I want to translate the "Out of stock" and "In stock".
I tried to sync on "Theme and plugins localization" but it didn't work out.
Also, I tried on "Translate texts in admin screens", and I found 2 matched strings of "Out of stock" and "In stock", I translated them but nothing has chagned.
Also tried to remove cache both from my website and the WPML plugin and still nothing chagned.
I attached also the code I added to my functions.php so you could see.
