Pay with a Like not showing like buttons (again)

No buttons are showing, and only Twitter appears, as a text link.

Seemed to be working fine last night, and today, not. I haven't installed any plugins in the meantime (though I may have added an image to the post I was working on).

Toggled script-loading on and off, still doesn't work. This has happened before, on a theme by an unrelated developer (last was Organic Themes, this is ThemeShift), both reputable.
