How to change zimbra login screen logo height?

Question

I have prepared a login image for my new e-mail system (Zimbra). Then I have changed hhe contents of file /opt/zimbra/jetty/webapps/zimbra/skins/_base/base3/skin.properties

...
90 LoginH1 = margin:0 0 30px 30px;
91 LoginAppName = display:none;
92 LoginLabelColor = @TxtC@
93 LoginButton = @ButtonShadowDefault@ border:1px solid @ButtonBorderColor@;
94 LoginBannerImg = @LogoImgDir@/LoginBanner.png?v=@jsVersion@

//95 LoginBanner = @img(, LoginBannerImg, 450px, 36px)@ //old
95 LoginBanner = @img(, LoginBannerImg, 450px, 90px)@ //new

96 LoginFooterColor =  color:@darken(AppC,55)@;
97 LoginErrorPanel =  background-color:#FF9; padding:5px; @roundCorners(8px)@
...

Eventhough I have changed the value 36px to 90px at line 95, it shows my custom login image at 36px height still. It is shown well on Internet Explorer, the image's whole view is not showed on Mozilla Firefox.

After page loads I have this CSS code at file /css/common,login,zhtml,skin.css?skin=serenity&v=131203105340 :

.ImgLoginBanner{
    background-repeat:no-repeat;
    background-image:url(/skins/_base/logos/LoginBanner_white.png?v=131203105340);
    width:450px;
    height:36px;
 }

Answer 1

I have restarted the server. It is ok now.

Answer 2

Just for ease - instead of restarting the server, this would have done the job immediately:

zmmailboxdctl restart
