send link

www.acleague.ro/newsite/

I don't see that image on that page, only thing that resembles it is separator between menu root items. To remove that:
template_css.css


#nav > li {
float: left;
position: relative;
border-right: 2px dotted #B5B5B5;
padding: 3px 20px 10px 18px;
margin: 8px 0 0 0;
}

remove border-right: 2px dotted #B5B5B5;

I've put

#nav > li {
float: left;
position: relative;
border-right: 2px dotted #B5B5B5;
padding: 3px 20px 10px 18px;
margin: 8px 0 0 0;
}

remove border-right: 2px dotted #B5B5B5;


and nothing. What is wrong ??
