[Resolvido] The translated product page returns a 404 error page

Background of the issue:
I am trying to resolve an issue with the translated product page on my site, hidden link, which is returning a 404 error page. I found the same issue here: https://wpml.org/forums/topic/the-translated-product-page-returns-a-404-error-page/, but I already have the last version (4.7.6).

Symptoms:
The translated product page returns a 404 error page. Instead of seeing the translated product, I got a 404 error.

Questions:
Why is the translated product page returning a 404 error?
How can I resolve the 404 error on the translated product page?
