Posts visibility

Hi everyone!

I am having a problem with my posts.

My new posts can be seen in their page (https://ciaomamma.it/news/) only by myself or the other contributor. This is what I see (https://s17.postimg.org/sw3zvm9r3/screen.jpg)

However, on other pages I don’t have the same problem (https://ciaomamma.it/lettere/) as you can see here. This post has been published on the 14th and it is visible by everyone.

However, if I give people the link they can access to the article and read it. I already checked the visibility and it’s set public everywhere.

Might it be a problem with the “Blog-in-Blog”? It’s what I am using to manage these two pages.

Any advice of what I could do? Thank you anticipatedly!
