Hi Marco,

Thanks so much for reporting this bug! I have confirmed the bug and opened a bug report here: https://github.com/raamdev/independent-publisher/issues/129

I’ll make sure this gets fixed in the next Independent Publisher update.

In the meantime, if you want to patch your version of the theme, you can modify inc/template-tags.php as shown here:
