Ok, I just got it working. I saw that you added your code in the css editor, so I made the change there.
Since the .site-header .wrap was showing up on top of the logo, I edited the code from this –
.site-header .wrap {
background: #ffffff;
}
To this –
.site-header {
background-color: #fff !important;
}
and now it shows on top.
