Only a guess but you might need global $post before your code. According to the Codex docs for the functions you are using the return values are Null if global $post is not set. Also you might want to use their suggested logicals: if (!empty( $prev_post ))

No. You’d have to change core WordPress functionality to achieve that (lots of work, and you’ll have to do it again for each upgrade). And if you’re finished with that, you’ll probably have to change some plugins as well. Generally, a big wp_posts table isn’t a problem. If your site is slow, look into where … Read more
Let me update your code 🙂 You don’t need to select grandparent category for your post. First we need to get grandparent category name. Here is the function; function get_grandparents_category_salgur( $id) { $parent = get_term( $id, ‘category’ ); if ( is_wp_error( $parent ) ) return $parent; if ( $parent->parent && ( $parent->parent != $parent->term_id ) … Read more
