I just installed Zimbra on a brand new server, and when I log on to the admin console I see "(data is stale)" next to all of the services. I searched the forum but only found posts referencing this as an error during upgrade or migration.
Considering I haven't upgraded or migrated anything - and I won't be migrating my current system, I'm just going to start from scratch - I don't see how this would play a role in me seeing this message.
P.S. The notify Zimbra link is broken. I confirmed this by trying to go to the notify URL in my browser and got a 404.
