在给一个zencart网站搬空间时，发现前台可以打开，但后台出现如下代码：

=============================

Warning: session_start() [function.session-start]: Cannot send session cache limiter – headers already sent (output started at E:\phpserve\APMServ5.2.6\www\htdocs\jerseysnflstore\admin2012\includes\classes\logger.php:106) in E:\phpserve\APMServ5.2.6\www\htdocs\jerseysnflstore\includes\functions\sessions.php on line 108

=============================

解决安案：

1.去下载一个：缓存设置同步工具：http://www.zen-cart.cn/tools/cache-sync

解压后：将FIX_CACHE_KEY.PHP上传到Zen Cart安装目录(与index.php同一目录)并运行，该工具用于迁移服务器后重置”SESSION_WRITE_DIRECTORY”的值。

（友情提示：完成后请删除该文件。非常重要!!!!! 否则别人可以利用它获取服务器信息，有安全隐患。）

如果还是出现，同样的问题的话，继续做下面的操作：

2. 打开： admin(你后台的目录)/includes/application_top.php

在代码：set_magic_quotes_runtime(0);  下插入：  ob_start();
