No, they don’t.
I suspect some kind of DB issue, as if the indexes aren’t fine.
On the “WP Show Posts” Support page I talked about an issue I had in the Home. It turned out that the issues I had whilst saving (connection with the hosting) saved the entry badly – no idea how, but it wasn’t showing at all (I have ONE featured post in the home – Italian version). I changed category, removing the correct one, updated the post and then I went back, setting the correct category and updated it: the featured article worked again.
But the Blog Post page is not managed by “WP Show Posts”. I tried the same solution, but still they’re not appearing, and it was happening even before activating the Code Snippet plugin.
That said, I checked on my cPanel for the hosting and the DB is fine.
Does it make any sense to repair it anyway, in your experience? (I have no idea if I can trust that system check.)
Thanks for your quick feedback.
