Question

我们刚刚将一个新的v6网站部署到一个主机上，该主机上运行了多个v4个网站，没问题。在前端，它看起来很好，但在Umbraco管理员中，内容和媒体树显示为空。

在浏览器调试器中，我可以看到TreeDataService.ashx中存在错误。

错误如下，我不确定问题是什么。是权限吗？数据库用户权限？

Answer 1

检查umbraco db连接字符串。

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

如果包含

的providerName =＆＃34; System.Data.SqlClient的＆＃34;

然后添加并检查。相同。它可能会开始工作。

Answer 2

问题是SqlSyntaxProvider为空，我的解决方法是init。

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

Answer 3

连接字符串，add name =“umbracoDbDSN”...缺少以下providerName =“System.Data.SqlClient”

一旦我将其添加到该行，就会开始工作。
