Facebook like button not showing

Hello, perhaps you can help me with an issue I am having at my website. I am using Sassy Social Share 3.3.20 to display a Facebook Like button at the bottom of my posts. I also have a Facebook button for sharing and a More button. I noticed today that the Like button does not show up anymore, although interestingly its empty space is still there (it was at the beginning of the line, so it’s visible).
The Facebook and More buttons are still there and working fine. Could you let me know how to get my Like button back? Thanks in advance.
