We are using the “POST NAME” structure for our permalinks. When we update the same post after it has been published after several months; we also change the post name at the same time; which effects the web URL at the same time. Whenever someone clicks on the old url; it shows an entirely different post on our blog. Is there a plugin or something that can fix this for us. We are using a plugin called Permalink Finder; but it still does not resolve the problem. Any help or suggestions would be appreciated.
