If Course Hero is not working for you, there are multiple possible causes and ways to troubleshoot. Here is the most common issues and how to fix them.
🔍 Common Problems
You can’t log in to your account.
The website or app won’t load or crashes.
You can’t access documents, e.g., “Unlocks not working anymore.”
You receive an error message like “.pdf invalid or corrupted.”
🛠 Troubleshooting Steps
Here are steps you can follow to try and fix the problem.
1. Check If the Issue Is Global
Use tools like “Is the app down” or the site’s status page to see if other users are reporting issues.
Check Reddit or support forums; for example, some users report crashes or network problems with the Course Hero app.
2. Clear Cache / Try a Different Browser or Device
If you’re using a browser: clear cookies & cache, then reload.
Log in via Incognito / Private mode to rule out extension/plugin interference.
Try a different browser or device (phone ⇄ desktop) to see if the issue persists.
3. Check App Version & Network Connection
If you’re using the mobile app, check if there’s an update in the App Store / Google Play. An outdated version might have bugs.
Ensure your internet connection is stable. Try switching between Wi-Fi and mobile data to rule out network issues.

4. Check Account & Subscription Status
Make sure your account is active and your subscription (if needed) is valid. Some features (like full access to documents) depend on subscription status.
If your account was suspended or terminated, you may lose access. There are complaints about this particularly from tutors.
5. Document Access Issues
If a PDF says “invalid or corrupted,” Course Hero suggests collecting logs from the browser’s developer console and submitting them to support.
For unlocks or viewing documents: ensure you meet the requirements (uploads, subscriptions, etc) and that there aren’t any browser extensions blocking scripts.
6. Contact Support
If none of the above fix your issue:
Use the Help Center on Course Hero’s website: submit a ticket with details of your issue.
Provide screenshots, browser version, device type, and description of the problem.
If problems persist after these steps, contacting Course Hero support is advisable for further assistance. Overall, the typical fixes are clearing browser data, checking internet connections, and waiting if the service is down temporarily.
