我的网站有时会在主页上获得303重定向循环。这在尝试查看网站“网页有重定向循环”时给出了错误，但大部分时间都是正常的。但是，303重定向对SEO来说并不好看。我正在使用Zo2框架运行Joomla 3.2.3。我使用了firefox live http header工具，这就是它显示的内容：
HTTP/1.1 303 See other
Date: Sat, 19 Apr 2014 06:42:44 GMT

我一次经历并禁用Joomla中的每个插件，当我禁用Zo2框架插件时，303重定向消失了。我在他们的论坛上问过他们无法帮助我。所以，我搜索了zo2插件目录中的所有文件中的redirect一词，这就是我找到的。
这两个位于site.megamenu.js
中!function ($) {
$(document).ready(function ($) {
// when clicking on menu
redirect();
var duration = 0;
var $parent = $('.zo2-megamenu');
var hover_type = $parent.data('hover');
if ($parent.data('duration')) {
duration = $parent.data('duration');
}
function redirect() {
$('.dropdown-toggle').on('click',function(e){
if($(this).parent().hasClass('open') && this.href && this.href != '#'){
window.location.href = this.href;
e.preventDefault();
}
});
}
我使用相同的.htaccess和php.ini文件在此服务器上运行其他网站，所以我认为这不是问题，因为他们没有获得重定向。我将不胜感激。该网站为http://www.betterfreestuff.com
