Hello,
1) You can change this here:
Template.CSS - Line 3
body {
background: url("../images/s5_background.jpg") no-repeat fixed center top / cover #dfdcdd;
color: #525252;
font-size: 1em;
line-height: 160%;
}
2) On the server in the vertex > footer.php file
3) Do you have the component disabled under the Home Menu Item in the Template Manager > General > Hide Component On Pages?
