Suppose I wrote an article, "My Article Title", it has been saved into the database with
$post_name=my-article-title , and the permalink is
mysite.com/my-article-title. All good.
Now, if I didn't like the title and change it to "Title of my article", I expect the post name and the url change accordingly. So the url should become
mysite.com/title-of-my-article, however, it remains as
mysite.com/my-article-title. So how do I set it to change?
Should I add a meta box somewhere? Or is there a plugin for this?
