Katie, we are not giving up this easily. Just to make sure I understand correctly:
You are using Windows 7. Your browser is Internet Explorer (the one that comes with Windows).
Can you tell me if your son followed exactly these steps?
- Open your browser. Press Ctrl+Shift+P for private browsing.
- Navigate to the problem link: https://www.mobileread.com/forums/usercp.php
- Go back to normal browsing. The link should be fine now.
Thanks!
