Umbraco v6 Deploy to production server getting DB exception, content and media trees not loading

问题

We just deployed a new v6 site to a host that has several v4 sites running on it no problem. On the front end, it looks fine, but in the Umbraco admin the Content and Media trees appear empty.

In the browser debugger I can see that there is an error in the TreeDataService.ashx.

The error is below and I'm not exactly sure what the issue is. Is it permissions? Database user permissions?

回答1:

check you umbraco db connection string.

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

if it do contains

providerName="System.Data.SqlClient"

then Add it and check. the same. it might start working.

回答2:

Problem is that SqlSyntaxProvider is null, my workaround is init it.

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

回答3:

The connection string, add name="umbracoDbDSN" ... was missing the following providerName="System.Data.SqlClient"

Once I added that to the line things started working.
