The related posts always seems to show the same 4 links. It doesn’t rotate between posts in the same categories. It only shows the same 4. When I click on one of the related posts to go to another post it then has 3 of the same related posts and then just the old post I clicked from. How can I randomize the posts it shows? I don’t want to go back to nRelate or Outbrain since they do not look as clean in the theme.
