I've removed the unnecessary code (I hope everything). The code looks like this one in this moment:

function saveOrder() {
    $(".column").each(function(index, value){
        var colid = value.id;
        var cookieName = "cookie-" + colid;
        var order = $('#' + colid).sortable("toArray");
        for ( var i = 0, n = order.length; i < n; i++ ) {
            var v = $('#' + order[i] ).find('.portlet-content').is(':visible');
            order[i] = order[i] + ":" + v;
        }
        $.cookie(cookieName, order, { path: "/", expiry: new Date(2012, 1, 1)});
    });
}

function restoreOrder() {
    $(".column").each(function(index, value) {
        var colid = value.id;
        var cookieName = "cookie-" + colid
        var cookie = $.cookie(cookieName);
        if ( cookie == null ) { return; }
        var IDs = cookie.split(",");
        for (var i = 0, n = IDs.length; i < n; i++ ) {
            var toks = IDs[i].split(":");
            if ( toks.length != 2 ) {
                continue;
            }
            var portletID = toks[0];
            var visible = toks[1]
            var portlet = $(".column")
                .find('#' + portletID)
                .appendTo($('#' + colid));
            if (visible === 'false') {
            }
        }
    });
}

var setSelector = "ul.widgets";
var setCookieName = "listOrder";
var setCookieExpiry = 7;

function getOrder_s() {
	$.cookie(setCookieName, $(setSelector).sortable("toArray"), { expires: setCookieExpiry, path: "/" });
}
 
function restoreOrder_s() {
	var list = $(setSelector);
	if (list == null) return
	
	var cookie = $.cookie(setCookieName);
	if (!cookie) return;
	
	var IDs = cookie.split(",");
	
	var items = list.sortable("toArray");
	
	var rebuild = new Array();
	for ( var v=0, len=items.length; v<len; v++ ){
		rebuild[items[v]] = items[v];
	}
	
	for (var i = 0, n = IDs.length; i < n; i++) {
		
		var itemID = IDs[i];
		
		if (itemID in rebuild) {
		
			var item = rebuild[itemID];
			
			var child = $("ul.widgets.ui-sortable").children("#" + item);
			
			var savedOrd = $("ul.widgets.ui-sortable").children("#" + itemID);
			
			child.remove();
			
			$("ul.widgets.ui-sortable").filter(":first").append(savedOrd);
		}
	}
}

I've solved the problem. In the Javascript code was a short .php code inserted. I've deleted the .php and now everything work fine. Thank you!
