[pine1455]

Hi,
I run the following command to redeploy yahoo theme .. but got exception error...
I'm using Zimbra Release 5.0.3_GA_2101.RHEL4_20080319090645 CentOS4 FOSS edition
Any Idea ?
==========================
[zimbra@localhost skins]$ cd /opt/zimbra/jetty/webapps/zimbra/skins/yahoo/
[zimbra@localhost skins]$ cp -a yahoo /tmp/new_yahoo

change the "SkinName" in /tmp/new_yahoo/skin.properties file as appropriate.

[zimbra@localhost skins]$ zmskindeploy /tmp/new_yahoo
