由于在设置 iThemes Security 时，设置 了服务器不支持的功能。导致网站无法访问。所以只能通过FTP删除 iThemes Security 插件，但是当再次启用插件时，以前的设置被自动加载应用了，所以判断 iThemes Security 在数据库中存储了配置。
说明：以下操作需要在懂数据库技术的前提下进行（操作前一定要备份数据库！！）
使用phpMyAdmin 备份数据库（方法自行百度谷歌）
指令
1。通过FTP或cPanel文件管理器,到此路径下：/wp-content/plugins/
2。将“better-wp-security”文件夹重命名为别的像“better-wp-security2”
3。插件被禁用,你可以开始管理工作了。
4。现在,重置。你可以通过你的控制面板(cPanel) 中的phpMyAdmin 访问数据库。
5。如果你有很多网站,找到你在操作的正确的网站数据库。您可以在wp-config.php文件中匹配数据库名称。
6。点击数据库名称选择和加载它。
7。在右边你会看到一个表列表。 注意:这是一个很好的时间导出/ 备份你的数据库。别怪我没提醒你。
8。删除表与“安全评估”,见截图 http://i.imgur.com/PHLITDW.png
9。去你的“options ”表,单击它。
10。通过“option_name”点击标题,并确保你有排序的所有行。
11。在option_name列中，行从字母I开始。
12。寻找“itsec ”选项。见截图。 http://i.imgur.com/MTqTn4h.png
13。选择所有。如果你在当前页面,确保你删除选项,检查下一个页面,以确保你得到它们。
14。一旦你删除这些选项。回到FTP /文件管理器。
15。重命名文件夹回到它原来的名字“better-wp-security”。
16。使用正常wp-login.php 登录到你的网站。。
17。去插件中激活这个 插件。
18。你又得通过设置,用它来保护你的WordPress。我们已经删除所有设置!
19。进行WordPressing。
20。还在这里吗?走了。
请小心和测试。 :)
