Hi Benjamin,

To fix header and primary menu at the top of the pages go to Appearance -> Theme Options -> Design Options Tab -> Custom CSS paste the following CSS code and Click on save button:

.hgroup-wrap,
#access {
    position: fixed;
    width: 100%;
    z-index: 100;
}
.hgroup-wrap {
    background-color: #fff;
    top: 0;
}
#access {
    top: 105px;
}

Thank you!
