ooops, your right, didnt see that on viewing the browser source sorry.
the progress bar is using the cabo sunset theme, so try editing this code in the webassist/progress_bar/jquery-blockui-formprocessing.js
WADFP_Theme_BaseOptions['CaboSunset'] = {
overlayCSS: { backgroundColor: '#656586' },
css: {
'-webkit-border-radius': '10px',
'-moz-border-radius': '10px',
width:'',
left:'',
border: '5px solid #fff',
backgroundColor : '#392F69',
color: '#D85F0E'
}
}
and add position and z-index to the overlayCSS:
overlayCSS: { backgroundColor: '#656586', position: 'absolute', z-index: '99999' },
