jquery menu and IE

I have this menu:

 <script type="text/javascript"> 
<!--//--><![CDATA[//><!--
$("html").addClass("js");
$.fn.accordion.defaults.container = false; 
$(function() {
  $("#acc3").accordion({initShow : "#current"});
  $("#acc1").accordion({
      el: ".h", 
      head: "h4, h5", 
      next: "div", 
      initShow : "div.outer:eq(1)"
  });
  $("#acc2").accordion({
      obj: "div", 
      wrapper: "div", 
      el: ".h", 
      head: "h4, h5", 
      next: "div", 
      showMethod: "slideFadeDown",
      hideMethod: "slideFadeUp",
      initShow : "div.shown"
    });
  $("html").removeClass("js");
});
//--><!]]>
</script> 
<!--<![endif]-->

    </div></div>

It works fine on Chrome, FF, Safari and on IE9. the problem is IE6, IE7 and IE8 the navigation gets hidden . I'm testing on IE6 and when I delete the Internet temporary files the menu magically appears without refresh the page.

This is the JQ accordion that I use

this is the Test Site Link

the error seems to take place in IE quirksmode (IE 7-9 standard modes do show the menu)

both Chrome and IE are throwing an error: Autocomplete is not defined

I don't think the issue is the accordian, try removing/fixing the following to see if the accordian works in IE6+

new Autocomplete('query', { 
    serviceUrl:'BuscaTermosProd.asp?IDLoja=12929',
    minChars:2,
    maxHeight:300,
    width:370,
    deferRequestBy:500,
    showResults:1,
    autoSubmit:false,
   onSelect: function(value, data){
     document.buscaprod.Texto.value=value;
     document.buscaprod.submit();
   }
});

the problem was about this css style:

.js #main .accordion {visibility:hidden}

I only deleted this and all worked fine.
