finick on "Polylang displays only English posts instead of other translations"

I wrote a regular post in a Spanish language, for instance. I set it to Spanish, then went to the blog page to see the posts, and I saw a default English news feed instead of Spanish. Same was for all 3 languages.
I attempted to perform the same thing for my custom post type, the problem was just the same, English posts were displayed instead of Spanish. I use Polylang 1.1.1.

What might the problem be? Everything used to work like charm a couple of weeks ago.

Since then I've written several posts recently via wp_insert_post and set their post terms and then used save_translations. I guess that's pretty much it.

Thanks,
Nick
