I'm running Zimbra 4.5.4.
Since upgrading to Firefox 3, it won't show / load the administrator (port 7071) login interface. I can only see blank page. But I have no problem with user login interface page.

To determine whether my zimbra has problem, I tried with IE6 & Firefox 2 on another pc. And it's able to load as usual.

Has anyone face this problem? Please advise. Thx.
