Conversation view not displaying subjects after upgrade
We've just upgraded from ZCS 5.0.x to 6.0.x. Initially there were problems logging in via the web interface, which we resolved by using the advice in this thread.
However we now have a separate problem. When viewing any inbox, if you expand a conversation to see the individual e-mails within listed, the subject area of the interface (that previously showed the first line of the e-mail) is now blank for all messages in that conversation.
Has anybody come across this problem before and can maybe suggest a fix? Or could this issue hint at potentially bigger problems with the upgrade?
Any help greatly appreciated!
