I cannot believe i did not try it before. To "fix" the "andrea" theme, all you have to do is add this in the "style.css" file of the theme:
It comes with: (line #487)
#footer {
background:#002a53;
position:relative;
font-size:11px;
color:#4e8abe;
margin:0 auto;
padding:10px;
width:680px;
text-align:left;
}
You have to add a "z-index":
#footer {
background:#002a53;
position:relative;
font-size:11px;
color:#4e8abe;
margin:0 auto;
padding:10px;
width:680px;
text-align:left;
z-index:-1;
}
And it will show correctly.
