Hey James,
Thanks a lot for taking the time to do it.
But, unfortunately, it looks like it doesn’t work completely. Now I can see the three strings in the WPML menu to translate them, but there are two weird issues:
1) The “Append Expiration Time to Pending Order Text” and “Append Included Items to Pending Order Text” gets translated to Spanish but not to Catalan (I have Catalan, Spanish and English). I press the save button but once I refresh the WPML String Translation menu, the Catalan translation is back to English.
2) It seems like the sessions are not synchronised between all the languages.
I’ve been with 3 different browsers with a private session and with my cache plugin deactivated, just in case.
Then, I add one item to the cart and I get the “not available” message, but if I change the language, I can add again the product.
If I change the browser, usually one language will have the “not available” message but the other 2 languages won’t have it. I haven’t been able to find a regular pattern.
By the way, my case is this “edge” case where I have 1 unit of each product.
Feel free to test it by yourself. The website is https://www.naikare.es/botiga, and from there you can change to Spanish or English.
Thanks again, and if you have any question just let me know.
