主题中的系统错误

Question

如下所示得到一些系统错误，我试图弄清楚为什么前端没有使用IE或safari登录，但是从日志中慢慢解决问题，关于这一点的任何想法，错误是第51,54行和67，

2015-05-12T13:46:34+00:00 ERR (3): Notice: Undefined offset: 1  in /var/www/vhosts/mfeuk.co.uk/httpdocs/app/design/frontend/mtorion/default/template/magenthemes/mainmenu/top.phtml on line 51

这是我的代码：
