WP Table Manager 插件未正确安装

WP Table Manager 使用自己的框架，该框架自动安装在 /wp-content/mu-plugins 中

有时这个目录有错误的权限， WP Table Manager无法安装它的框架。
要解决此问题：

创建文件夹/ wp-content / mu-plugins
确保/ wp-content / mu-plugins可被您的Web服务器用户写入
再次转到您的wordpress管理页面，并检查是否仍然存在该错误。

你还有问题

将wp-table-manager.zip文件的内容解压缩到本地计算机上
如果不存在，请在您的网站上创建文件夹 /wp-content/mu-plugins
将之前解压文件中的 /wp-table-manager/framework/ 文件夹的内容复制到网站服务器中的 /wp-content/mu-plugins/ 文件夹中
再次转到您的WordPress管理页面，您应该不再有错误
