I want to change my permalinks of WordPress Site. It is currently on /2013/12/23/sample-post/ . I want to change it to /post-name/ . If I change the permalinks the old posts url does not change. It stays the same (/2013/12/23/sample-post/). Does anyone know how to solve this?
Thanks in advance. My site url: http://www.techierevive.com
