facebook like button doesn't show up

I tried this in localhost of XAMPP. Should it be online to work?

Facebook icon doesn’t display for me either. Neither foes Pinterest even though ever post has a thumbnail. Only Google and Twitter displays.

I added to wp_config: define (‘WPLANG’, ‘en_US’);
Used to be: define (‘WPLANG’, ”);

That didn’t make a difference.

It won’t work on localhost (xamp/wamp etc.). Try online or set hosts in “hosts” file in Windows.

Facebook and Pinterest are not showing up on my site neither. https://www.studio197.co.uk

All 4 buttons have been set in setting screen to show after content on each post, page and homepage. Please help.

my fb like button is showing count but is not showing the count on my fb page. ????
