Hello,
Please try to add this code in custom.css file and disable fixed header in Theme Options > General > Enable Fixed Header > Off:
.header.main-header {
position: fixed;
z-index: 10000;
background-color: white;
width: 100%;
margin-top: 30px;
}
.top-bar {
position: fixed;
z-index: 10000;
width: 100%;
}
.wpb_revslider_element.wpb_content_element {
margin-top: 158px;
}
Thank you.
