What does "the challenge page was accidentally cached" mean? How do I fix it?
If you experience this error when trying to load a page, this is most likely due to a problem on your web browser, and not any problem with the site itself. You can resolve it by following the below steps:
1. Open Control Panel, and click Clock and Region, and then click Date and Time.
2. Click the Internet Time tab, and then click Change settings
3. Check the box for "Synchronize with an Internet time server with name" and set the server to this: time.windows.com
Then click Update now.
After doing this, try the website again and it will work!
