Playing in Zimbra 5.0.1 on F7 and all of a sudden I get this when accessing the admin console;
Firefox can't connect securely to mymachine.mydomain.co.uk because the site uses a security protocol which isn't enabled.
IE just gets an error page. I've been playing for days without a problem, all I did was modify the maximum size for email though I don't think it's related to the problem.
I have rebooted both the server and workstation but the problem persists.
