****请参见下面的编辑****
Edit added 1/4/2018 我按照指示重新开始。就我所知，一切都是正确的，包括同步插件。fpw同步用户。测试中的php。我们的网站。com 3出现$other\\u前缀=数组（\'wp5l\\u\'，）；fpw同步用户。论坛中的php。我们的网站。com 3$other\\u前缀的出现次数=数组（\'wp7g\\u\'，）；对吗？当我尝试登录任何一个站点时，会发生什么情况？它只是刷新登录页面，什么也没有发生。没有错误消息
****结束编辑****
我的组织正在使用WordPress 4.9.1。
我们希望实现的是让成员在secure上创建用户配置文件。我们的网站。org，当他们登录时，他们将有权访问论坛。我们的网站。组织。
我无法找到完成此任务的更新说明。这里有谁能告诉我需要做些什么来完成这项工作，或者从哪里获得最新的说明？
非常感谢。
****其他信息****我多次按照@Frank P.的指示在该链接上进行操作，但它不起作用。我不得不把一切都恢复到原来的样子。请看下面我采取的步骤，如果我做错了什么，请告诉我。
我尝试在其上测试单个登录设置的站点位于子域上：test。我们的网站。com和论坛。我们的网站。com公司
测验我们的网站。com的数据库前缀是wp7gforum。我们的网站。com的数据库前缀为wp5l
我想要测试。我们的网站。com是创建用户的位置。
我从论坛导出了所有数据库表。我们的网站。com（wp5l\\u user和wp5l\\u usermeta除外）并将它们导入测试。我们的网站。com数据库。
我进去编辑wp配置。按照Frank P.的指示，在这个链接上创建php文件Single sign on between two wordpress website他说两个wp配置。php文件必须相同，除了$table\\u prefix处的前缀，该前缀应显示其数据库的原始前缀。因为我想在测试中创建登录名。我们的网站。com，我复制了整个wp配置。php文件到论坛。我们的网站。com的根目录。
我去编辑论坛了。我们的网站。com的wp配置。php文件，并将$table\\u前缀更改为wp5l，然后将其保存。
我去编辑wp配置。php用于测试。我们的网站。com并添加了以下定义和保存。
定义（\'COOKIE_DOMAIN\'，\'test.oursite.com\'）//这就是我认为问题可能在于定义（\'COOKIEPATH\'，\'/\'）；define（\'COOKIEHASH\'，md5（\'test.oursite.com\'）；定义（\'CUSTOM\\u USER\\u TABLE\'，\'wp7g\\u users\'）；定义（\'CUSTOM\\u USER\\u META\\u TABLE\'，\'wp7g\\u usermeta\'）；
我将这些相同的定义复制并粘贴到wp config。论坛中的php。我们的网站。com并将其保存。
我在wp内容中为这两个测试创建了mu插件文件夹。我们的网站。com和论坛。我们的网站。组织机构
我创建了fpw同步用户。用于测试的mu plugins文件夹中的php。我们的网站。com并复制了Frank P的代码，然后将3个区域更改为“我的前缀”，并将其保存为如下所示。
$other_prefixes = array(
\'wp7g_\',
);
我创建了fpw同步用户。论坛的mu plugins文件夹中的php。我们的网站。com并从测试中复制了相同的代码。我们的网站。com mu plugins文件夹，因此前缀是wp7g，正如Frank所说的那样。我保存了它
非常感谢。
