I just upgraded a site from 4.6.1 to 6.0.0 and now the only thing that displays in the content tab in the backend is a "Content" node. The whole tree has disappeared but the site actually still works it's just that I can't reach any of the content in the backend (see screenshot):
Media, Settings, Developer, etc. tabs all appear to be working as normal.
If I right-click on "Content" I get "Create", "Sort", "Republish Entire Site" and "Reload nodes":
Create gives me the expected create dialog box but I don't want to try creating anything yet until I know what's wrong.
Sort throws the following error

Republish works without error re-creating the umbraco.config file in the App_Data folder.
Reload nodes appears to be trying to, well, reload the nodes, but nothing shows up in the end.
Please help. Version is "Umbraco v6.0.0 (Assembly version: 1.0.4779.24222)"
I'm experiencing a similar problem. However I can see the content tree.
When trying to add content to a node (right click + create), I get following error in the create popup window.
Has enyone been able to fix the problem?

No content showing in backend after upgrade to 6.0.0
