Hello,
I’m sorry to hear that you encounter so many problems while using our theme. We do extensive testing when we release each version and we did not encountered this issue. It’s a strange issue and I can’t reproduce it here. But I’ve made a more flexible code:
http://import.tagdiv.com/newspaper/td_set_post_settings.zip
Can you copy this file over the /wp-admin/content-metaboxes/td_set_post_settings.php in the theme folder.
If you find any other problems feel free to contact us and I can give you a full refund if you are not happy with our theme đ
