我们刚刚将一个新站点部署v6到一个运行多个站点的主机v4上，这没问题。在前端，它看起来不错，但在 Umbraco 管理员中，内容和媒体树看起来是空的。

在浏览器调试器中，我可以看到TreeDataService.ashx.

错误如下，我不确定问题是什么。是权限吗？数据库用户权限？

检查你的 umbraco db 连接字符串。

<add name="umbracoDbDSN".......

如果它确实包含

providerName="System.Data.SqlClient"

然后添加并检查。相同。它可能会开始工作。

问题是它SqlSyntaxProvider 是空的，我的解决方法是初始化它。

var service = new Umbraco.Core.Services.ContentService();
    SqlSyntaxContext.SqlSyntaxProvider = new MySqlSyntaxProvider();

连接字符串，添加 name="umbracoDbDSN" ...缺少以下 providerName="System.Data.SqlClient"

一旦我将它添加到行中，事情就开始工作了。
