I applied ZCS_8.03 update yesterday and cannot seem to update the logos. Since I have single domain so I follow this "http://wiki.zimbra.com/wiki/Changing_the_Logo_and_Theme_Colors_from_the_Admin_ Console" to customize themes and logos in my global settings and domain - NOT working. I also replace AppBanner.png and LoginBanner.png in the _base/logos and _base/logos/ZimbraInside - NOT working. It used to be a very easy thing to do in ZCS6. My based theme is set to Sand. What am I missing? Please advise.
