   I'm using Yinjie Soon's DF-Style Linked List plugin. Rather than modifying the theme I'm using, I'm using separate code to change the behavior of the links on my post titles:
   

   add_filter('post_link','df_fix_permalink');
   
   function df_fix_permalink () {
     if (get_the_linked_list_link() == '') {
       return get_permalink();
     }
     else {
       return get_the_linked_list_link();
     }
   }

   This works fine: for posts with a linked_list_url it changes the post title link to that URL. However, attempts to edit the post now end up in a 404. To edit a post, I must comment out add_filter().

   Any suggestions to fix this?

   Based on an example here I was able to solve the problem:

   add_filter('post_link','df_fix_permalink');
   
   function df_fix_permalink ($permalink) {
     if (get_the_linked_list_link() == '') {
       return $permalink;
     }
     return get_the_linked_list_link();
   }
