When looking at your site, I see 2 JavaScript errors:

These errors break all other features relying on JavaScript on your site, like the Jetpack sharing buttons.
Both errors appear to be created by your theme, and are most likely caused by some changes to the version of jQuery in WordPress 4.5:

I’d recommend that you get in touch with your theme author about the issues. They should be able to help!
Thanks a lot for your quick reply. Unfortunately, the theme was made using Artisteer 3.1 software and I have no idea how to access jquery errors. Can they be accessed using Theme Editor within WordPress Control Panel?
I solved this problem by editing “script.js” file found in the theme folder, using instructions given in pages you linked. Now FB likes counter works, although I could not figure out how to identify “Uncaught SyntaxError: Unexpected token”. I guess it has something to do with brackets…
Thank you very much for your support.
