Hi all! I changed my SEO plugin a few weeks ago from All In -One to Yoast´s plugin,and I decided to change as well my permalinks format from this: mysite.com/888/new-post/ to this one: mysite.com/new-post/ So I wrote a few posts and then I realized that the new plugin changed the permalinks from the old posts, so the backlinks they had now are pointing to an URL that doesn´t exist anymore. I tried to change the permalinks manually, but the plugin doesn´t let me insert the slash. Is there a away to change that using code? or should I create pages with the old URL and redirect them to the new one?
