After upgrading our Zimbra server to 6.0.2 (Upgrade process was smooth and perfect), we noticed that the web client interface for Linux desktop is displaying just text all over and no functionalities.
Our server is running on Linux Ubuntu 8.04LTS.
For windows desktop users, everything seems to be normal.
The linux desktops are running 8.04, 9.04, and 9.10. All using firefox browser's current version (3.5). All linux station also have their java engine installed.
Any idea out there why is this happening for web client users using linux?
Would really appreciate for any feedback and assistance on the matter.
Thank you very much in advance.
