Why is the header showing when scrolling the page and how to fix it

Is your header still showing when the page is scrolled up even after setting your header to NONE?  

This is because a javascript code is automatically modifying the css for the header part (when scrolling to and from the top part of the page). 

To override the javascript code go to your admin site and in your dashboard go to Appearance > Customize > Code > CSS code.  Copy the code below and paste it in the field for CSS code.

.fl-page-header { 
display: none !important; 
}
