I removed that thread since our terms of service require that the footer credits are kept in tact and that thread was giving advice that goes against those terms. WordPress.com does require you to keep the footer credits.
Can you please remove the following from your custom CSS?
#footer {
display: none
}
#newfooter {
text-align: center;
position:absolute;
bottom:0;
left:0;
background-color:#e9e9e9;
padding:10px;
width:916px;
margin-top:10px;
border-top:1px solid #ccc; -webkit-border-bottom-right-radius:8px; -webkit-border-bottom-left-radius:8px;
border-bottom-right-radius:8px;
border-bottom-left-radius:8px
}
#newfooter a {
color: #2a2a2a
}
You can add text to a footer using CSS only. Here's an example showing how to do it:
#themeinfo:before {
content: "All content herein © 2012 KristinBlack. ";
}
