since yesterday the contents of my WordPress dashboard have disappeared. I installed quite a few plug-ins on my new installed blog and at some point the contents where gone.
The Dashboard page itself shows up but there is no 'Right Now' and any of the other content boxes. This happens if I click the link at the top to go to the dashboard (which is http://blog.hexagonstar.com/wp-admin/admin.php?page=index.php). But if I only enter http://blog.hexagonstar.com/wp-admin/ in my browser the dashboard will show correctly.
I've also tried it with deactivating all plugins but it didn't change back to showing the dashboard.
Anything known on this problem or how it could be fixed?
