Article 7: Fixing Video Lag, Freezing or Loading Errors

If your video is lagging, freezing, or showing a black screen, it is usually caused by a conflict in your web browser. Follow these steps to return to your lesson.

1. Try "Incognito" or "Private" Mode

Open your browser's Incognito or Private window and log in to the course.

• If it works: One of your browser extensions (like an Ad-Blocker) is interfering with the player.

• The Fix: Disable your extensions one by one to find the culprit.

2. Clear Your Browser Cache

Old data stored in your browser can cause loading errors.

• The Fix: Go to your browser settings and Clear Cache and Cookies. This resolves about 90% of all playback issues.

3. Check Your Browser Version

The Summoner School player works best on modern, updated software.

• Recommendation: Use the latest version of Google Chrome or Firefox. Avoid using outdated browsers or Internet Explorer.

4. Turn Off Your VPN

Some Virtual Private Networks (VPNs) slow down video streaming to prevent high data usage.

• The Fix: If your video is buffering, disable your VPN and refresh the page.
