Hi guys. I am working with SME 7 on a test server. After using the software installer tab of the server-manager to update my installation, the server-manager itself looks "bad", like it's no longer using the css sheet.

Rebooting the server has nad no affect, likewise restarting httpd-admin has not made any difference to the situation.
This has happened twice. Does anyone know what's happened and how to fix?
Thanks in advance.
