刚才我在后台开启seo的设置后，主页页头出现以下错误：

（Notice: Undefined index:  query in /home/justbuy/public_html/catalog/model/tool/seo_url.php on line 13Notice: Undefined index:  query in /home/justbuy/public_html/catalog/model/tool/seo_url.php on line 13Notice: Undefined index:  query in /home/justbuy/public_html/catalog/model/tool/seo_url.php on line 13Notice: Undefined index:  query in /home/justbuy/public_html/catalog/model/tool/seo_url.php on line 13Notice: Undefined index:  query in /home/justbuy/public_html/catalog/model/tool/seo_url.php on line 13Notice: Undefined index:  query in /home/justbuy/public_html/catalog/model/tool/seo_url.php on line 13)

网站的标志也不见了，无法点击进入其他页面，只有主页打得开
关掉seo设置也没用...是不是我做少了步骤？

求高手帮忙，感激不尽啊！！！
