[Cerrado] My site is not transalating

Background of the issue:
I have set up the primary settings for WPML on my site, enlace oculto, to translate it automatically for users. I want the site to be available in English, Spanish, French, and Portuguese.

Symptoms:
The site is not translating automatically. When I click on any country flag in the menu, it redirects me to the homepage instead of translating the page.

Questions:
Why is my site not translating automatically with WPML?
How can I fix the issue where clicking on a country flag redirects to the homepage instead of translating the page?
