I'm trying to submit an assignment for which I have to attach two files, but every time I hit "Submit Assignment," it won't let me, giving the message , "Attached files must be greater than 0 bytes." Well, they are. For reference, the two files I'm trying to upload are a 13.5 KB Microsoft Word Document and a 1.75 MB PDF File. I tried to attach the files, here, but that, too, failed, giving me the message, "An unexpected error has occurred. Please make sure that your session did not expire while viewing this page." I have, however, attached screenshots of both the original issue and this new one. This assignment is due at 11:59 PM EST (UTC-05:00) tonight, so I really need this issue solved quickly. Can somebody please help me?
