I just installed an update to Moodle from 2.2.1 to 2.2.2 on a Windows 7 server. All things seem well with one exception. In two particular courses (and could be in more), some upload activities when clicked on by students, or clicked on by teachers to edit, leads to a blank, white window with the message "The service is unavailable." It's not happening to all upload activities in these courses. I do know that these upload activities have had some large uploads from students, but I also know that these files were available to view and even download together as zipped folders as recently as minutes before the 2.2.2 update was installed. I can still create new upload activities in these courses and they do work.
I'd appreciate any suggestions for solutions as the student work already submitted is now inaccessible.
