The redirect problem with shopex synchronizing ucenter caused script not to run

First this question comes from this post

http://hi.baidu.com/fire_love_live/item/247276cfda421217b67a24c7

Just to be clear, it's not 15 that need to be changed,

The one about the wrong login password should not be changed

It's about line 557

$this->nowredirect('failed',base64_encode(str_replace(array('+','/','='),array('_',',','~'),$_POST['ref_url'])),__(' The user name or password is incorrect. Please enter it again '),$_POST['from_minipassport']);

The above nowredirect is not recommended to be changed to splash
