Hi all

I'm working on a site that needs expanding and one of the url's needs the file extension removing .php so I can page/extra-content and so on...
My problem is this page has a good amount of likes but once I remove the extension everything is back to zero.

site.com/page.php (100 likes)
site.com/page (0 likes)

Is there a way to keep the likes after I've removed the extension?
