For url_alias facebook like not save.

hello,

I think I have successfully update my site to friendly Url, I change the .htaccess.txt to .htaccess only,

Then I change the settings in admin- settings-settings.

I change the catalog/controller/common/seo_url.php file already

and I add the Url_alias I want


Its all working fine except to facebook like

In this link I have 8.1K Facebook like

But When I use the url_alias link It was gone.

I am searching to all forums but I dont get an answer Hopefully someone can help me.

Thank you so much

Facebook saves the url which is liked. If your page is liked with some page with earlier url and you change the url, it is new page for facebook. This is my assumption.
