I recently upgraded an install from FC4 zimbra 4.5.11 to CentOS 5 zimbra 5.0.2.

I have gotten virtually everything working, except for a major bug in AJAX view. Currently clicking on an email in AJAX results in a blank reading pane, and double clicking a message results in nothing. Standard HTML view works fine, however.

How do I go about diagnosing the problem, and in the interum can I disable AJAX so I don't have 3000 confused students complaining to me? Thanks!
