- What times show on the dropbox? Are you past the deadline? Did your professor set the wrong time (i.e. programmed a time that's different than what they stated)?
- Refresh the page and try again.
- Try signing out, then logging back in and trying again.
- Try submitting from a different browser (i.e. if you're in Chrome, open Firefox or Edge instead).
- Ask for help from the professionals: VLAC (Virtual Learning Assistance Center) or OTS (Office of Technology Services).
If none of that works (or while you're waiting for a resolution from VLAC or OTS), email your professor.
- Politely explain that you've tried to submit online, what you've tried instead (the above suggestions), and that it's still not working. Including screenshots wouldn't hurt.
- Attach a copy of your assignment to the email as proof that you aren't trying to sneak an extension on the due date.
