Somehow my sample portals broke...
Well, just the enterprise and development samples, but still, they don't work.
When I click on the link from /portal/welcome, I get a page that says:
A serious error has occured in the Desktop. This may have been caused by a mis-configuration on the server.
Please report this problem to your administrator.
Possible cause :
* You do not have permission to access the desktop
How should I go about debugging this?
