Hello,
1) Remove the bottom: 0; part from the coding below to fix the bar location.
s5_responsive_bars.css - line 317
#s5_responsive_mobile_bottom_bar_outer {
bottom: 0;
height: 48px;
left: 0;
overflow: hidden;
position: absolute;
width: 100%;
z-index: 2;
}
2) You have some 3rd party extensions loading javascripts. Try disabling these and clearing the cache as there is most likely a conflict.
