Buttons breaking different lines and browser issuess

Hi,

(example page)

I don’t know why, but there is an issue with the buttons as the Google+ button breaks into another line and the LinkedIn share button does not appear when using Safari.

In Firefox the LinkedIn button does appear but is broken between the LinkedIn logo and the number of likes, which are on seperate lines. The same issue happens in Chrome. In any of the browsers mentioned the Goole+ button appears on another line than the Facebook and Twitter button. I played around with the button sizes but couldn’t fix it that way.

I would appreciate your help. Thanks!
