title: Permalink Redirect from /%postname%/ to /%postname%.html in Wordpress Hosted Blog
body: <p>I've just changed my permalinks from <code>/%postname%/</code> to <code>/%postname%.html</code></p>
  
  <p>So, links which are in <code>/%postname%/</code> are showing <code>404</code> error. </p>
  
  <p>I want to redirect those links to <code>/%postname%.html</code> in order to avoid 404 error page.</p>
