Also, with regards to add task error, when I checked the server log, I see this error:
[23/Aug/2005:15:45:26][752.6020][-conn:projop::0] Notice: ad_page_contract tmpfile filter on variable 'upload_file.tmpfile' at URL '/evaluation/admin/tasks/task-add-edit': The tmpfile given was 'C:/WINDOWS/TEMP/AOL7F.tmp', and the list of valid directories is '/tmp /var/tmp'.
Any ideas?
