WayBack throwing “Wayback Exception An unknown exception has occurred. Unexpected Error” usually indicates a cookie problem
Posted by jpluimers on 2017/12/22
If saving a web-page on the WayBack machine throws you this error on any site:
Wayback Exception
An unknown exception has occurred. Unexpected Error
Then usually the cause is having too many cookies.
Clean your cookies for web.archive.org, then try again.
