I have migrated from Jira 4.3.4 to Jira 4.4.1. Everything seems to run fine except the portlets for a fast work log. When I enter the time and hit the "Add" button, then the browser pops up an empty dialog. The title of the dialog window is: "The page at localhost:10080 says:". When I confirm by hitting the OK button, then the window closes with no time being logged.
