Jetpack – Social buttons are transparent

Hi,
I’ve been using jetpack for a while, and never had any problems with my previous theme. The social sharing icons were all in color exactly like in the jetpack preview.
Since I got a new theme they show as transparent. I can barely see them at the end of each post. Basically I can only see the numbers.

Here is my site: mediterranealicious.com

I don’t know how to use css… Hope there is another fix to this??

thanks!
