Can you replace this one
#sf-newsletter-bar .sub-code>form input[type="submit"] {
margin: -63px 0 17px 460px!important;
background: rgba(255,255,255,0.78)!important;
}
by this one
#sf-newsletter-bar .sub-code>form input[type="submit"] {
margin: -63px 0 17px 540px!important;
background: rgba(255,255,255,0.78)!important;
}
It was a little adjustment on the margin left.
