[Resuelto] Language switch issue

Background of the issue:
I am trying to ensure that visitors to my site, enlace oculto, can navigate beyond the main opening page. As an admin, everything works fine, but I encounter issues when logged out.

Symptoms:
When I am a logged-out visitor, I can't leave the main opening page. Clicking on any link redirects me back to the welcome page repeatedly.

Questions:
What should I do to prevent visitors from being redirected back to the opening page?
Why are all visitors navigated back to the opening site repeatedly?
