This is quite a common problem. Facebook caches (stores) URLs on the server-side once and we are not sure they ever refresh to account for changes.
A good workaround would be to change the URL to http://yoursite.yolasite.com/index.php?page=new) and it should pull the new name and information.
Note: Replace yoursite.yolasite.com with the site URL.
