Reply To: Transparent Header issue after upgrade

The function should work if you’re using the “Content” area inside the Page Header metabox.

If you’re not using that content area, you’ll need to re-apply the absolute positioning.

Try adjusting the above CSS to this:

.generate-merged-header .site-header {
    position: absolute;
    top: 20px;
    left: 0;
    width: 100%;
    z-index: 1000;
}
