I'm posting this again, properly.

I've posted about a problem yesterday, but I think I did it wrong, posting it as if I were requering an "answer", when I have a problem. 
The option to share my rating on social media isn't showing up anymore. I don't know why I have this problem again.
I had this same problem a few weeks ago and a staff member solved it. But it happened again. The option to share my rating on FB, TW... isn't showing up anymore. I don't know if it is a site's bug or something.
This is how it used to appear in my FB profile: 

I'd really appreciate if someone can help me solving this.
