Well, I don't know why my last topic was deleted..
I'll try again:
I'm using the Open Source version of Zimbra (5.0.11) in a Centos 5 (64bit).
I can't create new accounts for 2 versions now, 5.0.10 and 5.0.11 (at 5.0.9 it was working fine).
The error that I get is:
I already tried, firefox, safari, IE 6/7.. none of them work!
Thanks for anyone that help!
