I cannot get the URL zimlet to show up in the ZWC zimlet pane. Other zimlets do show up. Here is the deployment messages in mailbox.log:

zimlet - Deploying Zimlet com_zimbra_url in LDAP.

Zimbra Admin client shows that it is Enabled in the default COS and in the Manage Zimlet tab but when logging in to the ZWC, it does not show up. Any help would be appreciated.
