We don't do this very often, so I don't know when it broke, but now when any admin clicks on edit for a User or a Group, we get a blank screen and nothing happens. We've restarted Apache Tomcat (Windows Server 2008 R2 x64), but it still does not work. I have no idea what else to do, except to rip the Wiki out and start over, restoring backups. -- View this message in context: http://xwiki.475771.n2.nabble.com/Unable-To-Edit-Users-Groups-tp7585850.html Sent from the XWiki- Users mailing list archive at Nabble.com.
