Students and instructors have reported problems uploading files into Blackboard using the Firefox 3 web browser. Specifically, when attempting to upload an attachment to an assignment, a javascript error message pops up: "Please enter a valid file", even when the file is valid. This issue only appears to occur in Firefox 3 on a Windows machine. Firefox 3 on a Mac or Linux system seems to work fine.
IT is working with Blackboard to develop a solution for this issue.
In the meantime, IT strongly recommends students and instructors use Internet Explorer (IE) or Firefox 2 to upload attachments to assignments in Blackboard.
IT will send out a follow-up announcement when this issue has been resolved.
