Like button not showing?

I used the plugin for more than 6 months, with out any problems, this plugin is amazing! But now all the sudden, the like button is not showing inside the locker, both in admin and front end. I tested it in different browsers and on 2 different sites. I pasted 2 screenshot of both admin and front end:
