Remove line under sidebar’s word

Are you referring to the links in the RHS bar?

If so then its a css issue. You may have got a quicker response if you’d posted in Themes and Templates forum.

From what I can see, it seems to be coming from the following id:

#sidebar-right ul li a{
     padding-left: 16px;
     padding-bottom: 5px;
     padding-top: 6px;
     border-bottom: #c0c0c0 1px solid; <<<strong>Here is where its coming from </strong>
     color: #333333;
     background: url(images/bullet-orange.gif) no-repeat 3px 12px;
}

Hope this helps

Just remove or edit the border bottom declaration
