is it function.php in the child theme or functions.php as in the parent theme?

@leejosepho:

Thanks for replying! I think it did ask for a DB update, and I ran the update, and even if something got corrupted in the process, everything else seems to work fine, except for them, featured images.
Even when I create a new post, the featured image is not rendered. It shows in the sidebar of the post editor, but does not make it to the pages…
