I just installed my first 4.5. Been running zimbra since 4.0 with no problems.

Logins to the 'advanced' interface fail with a network service error. I tried Firefox and IE. I also tried to set the default zone in the class of service. The text of the error is this:

code - service.FAILURE

Any ideas?

Thanks.
