title: Redirect Wordpress Permalink in htaccess
body: <p>I want to change the permalink structure of my site from /%postname%/ to /%category%/%post_id%/%postname%/ , and have the old backlinks redirect to the new structure (currently getting 404's). I have tried a couple of different redirection plugins (Redirection, 301 Simple Plugins) and I can't get them to work. </p>
  
  <p>Can someone show me the rule to put in the htaccess file instead?</p>
  
  <p>Thanks!</p>
