Invalid File Error While Submitting Assignments
Details
Receiving and error message "Please enter a valid file" when trying to submit a file when using the Assignment Feature.
Using anything other than Internet Explorer (version 8 or 7), Firefox version 3.0 or Opera 10 will receive this error.
At this time Safari and Firefox 3.5 work on Mac OS. This seems to be a Windows issue ONLY*.
*Linux has not been tested as of yet.
Work Around
For now, we do not recommend upgrading to Firefox 3.5, Firefox 3.0 will work with the assignment feature file submission. If you have upgraded to Firefox 3.5 and would like to uninstall 3.5 and reinstall 3.0 please follow these instructions:
- Download previous Firefox version 3.0.13 - do not install.
- Uninstall vers. 3.5 through Add/Remove in your control panel.
- Reboot.
- Re-install vers. 3.0.13.
If you use Google Chrome, Opera or Safari for Windows you will at this time have to use either Internet Explorer version 8 or 7 or Firefox 3.0 to submit assignments using the Assignment Feature.
