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?
