Hi There,
Thank you for writing in! First things first, please address the class secondrow, right now it has a pretty quotes on it (http://prnt.sc/ed4con) or else the custom CSS below will not work.
And then as you can also see my screenshot the second icon is not showing, it has a wrong image source URL.
To add gap between the social icons, please add this on your custom CSS.
.x-topbar .secondrow a {
margin-right: 12px;
}
Cheers!
