First, I'm running this version:
Release 6.0.6_GA_2324.RHEL5_64_20100406150533 CentOS5_64 FOSS edition.I have applied the latest patch.
I'm getting closer to rolling out ZCS in our business, but have encountered a problem I don't know how to solve. When I logged in to webmail as administrator, the display was missing some elements (tabs) and some parts were positioned on top of others. See the attached screenshot. My web browser is Firefox 3.0.11.
The first time I encountered it, I tried clearing the browser cache, logging out and back in, and restarting the browser, but nothing helped. Next I restarted zimbra, and the problem resolved itself.
The next morning, I logged in again and was trying the different client modes (Ajax, HTML, mobile). When I switched back to Ajax, the page is scrambled again. I tried the clearing the cache, etc. (as above) without success. I also disabled all my Firefox extensions/add-ins and our proxy server, also without success. I don't want to have to restart the server each time this happens.
Has anyone else had a similar problem? What am I missing?
