[Cerrado] WPML Plugin

Background of the issue:
I am trying to publish a new page on my website enlace oculto and have translated it to Arabic using WPML.

Symptoms:
When I change the language to Arabic on the website, it shows a 404 error page, even though everything is translated and updated.

Questions:
Why does the translated page show a 404 error?
How can I fix the 404 error for the Arabic translation?
