我们查看了类似的帖子，这些帖子提到纠正
open\u basedir
错误，但创建
vhost
并没有解决问题，我们根本不知道该怎么办

以下是添加
vhost
后的
错误日志的副本，使用以下说明：

感谢您提供的所有帮助：）
您的
www
文件夹中的文件权限设置不正确：
您应该为
www-data
用户（组）设置项目中的文件和文件夹的可读性

在下面的命令中，如果服务器中有多个项目，并且只有当前项目有问题，请将/var/www更改为您的项目根目录

您应该设置可写，哪些文件需要由php编写：

sudo chmod g+w /var/www/vhosts/***/httpdocs/wp-content/plugins/ultimate-tinymce/css/mce_modify.css
//repeat this on all file need to be written by your webapp

好的，所以我需要使文件可读，但哪些文件以及如何做到这一点？如何将/var/www更改为我的项目目录？如果您能更具体一点（关于步骤），我将非常感谢Kovge:）这段代码到哪里去了？！？！？！？！
sudo chmod g+w /var/www/vhosts/***/httpdocs/wp-content/plugins/ultimate-tinymce/css/mce_modify.css
//repeat this on all file need to be written by your webapp
