Solved: The Zimbra NG Modules does not appear in Zimbra Admin

Few days ago, I installed Zimbra 8.8.15 to replace the old Zimbra on my client. The installation process running well as usual. When installation finish, I’m logged in to Zimbra Admin and notice Zimbra NG Module does not appear in Zimbra Admin. I am using Zimbra NE for 2,5k users. So, for the workaround, I try some method below

1. Reinstall Zimbra NG Modules
Redhat/CentOS

yum update -y
yum reinstall zimbra-network-modules-ng
su - zimbra -c 'zmmailboxdctl restart'

Ubuntu

apt-get update -y
apt-get install --reinstall zimbra-network-modules-ng
su - zimbra -c 'zmmailboxdctl restart'

If reinstall zimbra-network-modules-ng did not work, please try to reinstall Zimblets

2. Reinstall Zimlets
# Undeploy Zimlets

su - zimbra
for zimlet in `ls -1 /opt/zimbra/zimlets-deployed`; do zmzimletctl undeploy $zimlet; done

# Deploy Zimlet Defaults

for zimlet in `ls -1 /opt/zimbra/zimlets | grep -v click2call | grep -v ucconfig`; do zmzimletctl deploy /opt/zimbra/zimlets/$zimlet; done

# Deploy Zimlet for Zimbra NE

for zimlet in `ls -1 /opt/zimbra/zimlets-network | grep -v click2call | grep -v ucconfig`; do zmzimletctl deploy /opt/zimbra/zimlets-network/$zimlet; done

# Flush Cache

zmprov fc zimlet
zmmailboxdctl restart

Now, the Zimbra Network NG module appears again in Zimbra Admin

Good luck 🙂
