这是对旧文中提到的wordpress访客记录的一次升级版，照样很简陋，算作给自己玩的吧；谁需要的话，也可以拿去玩。

<p>您需要创建一个表，用于 <strong>fs trace</strong>存储wordpress的将追踪记录. 该表默认位于数据库 log 中。如果您不方便创建一个名为log的数据库，可以将该表放在当前数据库中，只是要修改一下<strong>fs trace</strong>源码了，到wordpress仪表盘 - 插件 - 编辑 - fs trace, 找到这样一行 \" \$sql=\"insert into `log`.`wp_trace_{$wpdb->prefix}`... \", 改成 <pre>\"insert into `wp_trace_{$wpdb->prefix}`...</pre> (就是删除 <i>`log`.</i>),保存。 </p>

使用说明
wordpress后台，通过上传zip文件方式上传该插件，（或解压后，连目录上传到wordpress下 wp-content/plugins/ 目录），启用插件，然后到打开前台任意页面，照错误提示操作。消息提示有中英两种语言。提示文字可能因为您的模板关系而排版错乱，看起来有些费力。
本插件不会自己创建数据表，需要您按消息提示手工创建。
本表默认在一个名为log的数据库里，因为追踪表通常会比较大，可以减少wordpress主数据库体积，主要是方便备份。单独。如果不方便创建这个数据库（如在虚拟主机上，主机商通常只给一个数据库），可以修改本插件源码，上述错误消息里也有提示。
