Sadly I am still using release 5.0.16_GA_2921.UBUNTU8 UBUNTU8 FOSS edition.
The problem is:
User cannot get into Preferences of his account.
On IE (every version) and firefox shows icon about error in script on page, which says that something failed to load (I did not write down exact error text ).
On chrome everything works fine
In mailbox.log I have found:
Restarting zimbra (zmcontrol stop && start) solved this issue, and now everything works fine...
2010-06-25 13:30:29,646 WARN [btpool0-117]  log - /zimbra/js/Preferences_all.js.zgz: java.io.IOException: Permission denied
Can anyone point where to search for explaination of this error?
And how to make sure that it won't happen again?
I wasn't changing anything on the server for quite some time...
