next_posts_link() and previous_posts_link() both check if ( ! is_single() ) to display pagination. Now, is_single() is true in your case, because you are in a single post of 'author' type, so those functions can't work as you expect.The function is setup to use get_query_var() to check for page/paged but I cannot seem to make the URL /page/2 work. Instead I get a 301 redirect back to the continent.
