We've had Zimbra 5 installed on Ubuntu 7 for a month or so now. It's been working well. However, the admin page is not opening anymore.
I try to visit http://xyz.com:7071/zimbraAdmin, and I get a download style box for an "application/octet-stream" item (using Firefox 22.214.171.124). When I try IE, the page keeps trying to load.
I've restarted Zimbra using zmcontrol stop, zmcontrol start. zmcontrol status shows all as running. I've restarted the server as well.
Any ideas on where else I can look?
PS: Normal mail functions work fine (webmail, IMAP, etc).
