Hi,
It happened to me when I removed the category menu (subnav). So when you remove this you should remove as well 2 pieces of javascript, located in header.php
——————————
<script type=”text/javascript”><!–//–><![CDATA[//><!–
sfHover = function() {
if (!document.getElementsByTagName) return false;
var sfEls = document.getElementById(“nav”).getElementsByTagName(“li”);
// if you only have one main menu – delete the line below //
var sfEls1 = document.getElementById(“subnav”).getElementsByTagName(“li”);
//
for (var i=0; i<sfEls.length; i++) {
sfEls[i].onmouseover=function() {
this.className+=” sfhover”;
}
sfEls[i].onmouseout=function() {
this.className=this.className.replace(new RegExp(” sfhover\\b”), “”);
}
}
// if you only have one main menu – delete the “for” loop below //
for (var i=0; i<sfEls1.length; i++) {
sfEls1[i].onmouseover=function() {
this.className+=” sfhover1″;
}
sfEls1[i].onmouseout=function() {
this.className=this.className.replace(new RegExp(” sfhover1\\b”), “”);
}
}
//
}
if (window.attachEvent) window.attachEvent(“onload”, sfHover);
//–><!]]></script>

Just remove the code in bold and it should be working fine.
