Umbraco v6部署到生产服务器,导致数据库异常,内容和媒体树无法加载

Question

我们刚刚将一个新v6站点部署到主机上,该主机上v4运行了多个站点没问题.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,我可以看到存在错误TreeDataService.ashx.

错误在下面,我不确定问题是什么.是权限吗？数据库用户权限？

检查umbraco db连接字符串.

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

如果包含

的providerName = "System.Data.SqlClient的"

然后添加并检查.相同.它可能会开始工作.
