火狐访问报错
The page isn’t redirecting properly

Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

This problem can sometimes be caused by disabling or refusing to accept cookies.

google 报错

This page isn’t working ***** redirected you too many times.
Try clearing your cookies.
ERR_TOO_MANY_REDIRECTS

前台一切正常，就是进入后台报错，然后一直重定向还后面加上了一大堆跳转。
求大神出出点子！！！
