I am trying to show an static page instead of posts. It is defined accordingly in Settings-Reading, and it works fine. It uses a front-page template. But activating Polylang (since my web should be in several languages) causes a posts list to appear in home page, ignoring the setting of an static page, and using an index.php template.
I have read posts on that situation but definitely I am not seeing the clue. I would like to trace where WP takes the decision, but I am not proficient enough in debugging.
I would like to have some guidance to trace this behaviour or see what I am doing wrong.
