Switch to the Basic Uploader
Schoology uses a flash uploader to allow multiple uploads at a time and to show upload progress. However, users with certain setups might experience trouble with this uploader, particularly those behind a proxy. If you continuously get errors with the default uploader, you can opt to use the basic uploader, which can only upload one file at a time for maximum compatibility across platforms and networks.
To switch to the Basic Uploader, follow these steps:
1. Log in to Schoology and go to your Account Settings.
2. In the Account Settings tab, scroll down to the bottom of the screen to find Other Options and under the File Uploader section, click on Basic.
3. Click on Save Changes.
4. If successful, you should see this message at the top of your screen.
