Social Link Hidden

Hello to everyone,
My social link are hiding to my menu bar – theme Admired

http://www.weamirisolar.eu

I read the problem maybe a bug…
I think it is possible to solve the problem changing something in style.css. Unfortunately I’m not very pratice of css or php and I don’t have idea how I can change it.

Somebody had the same problem? How did you solve it?
By the way, could you suggest me a good pluging that work with my theme? I tried a lot of pluging about, but none have worked.

Thanks a lot

Vale
