Archive.org and Archive.today URLs have a 14-digit snapshot timestamp.  This error message is displayed when the archive snapshot date is not the same as the date stated in {{para|archive-date}}.

To resolve this error, make sure that {{para|archive-url}} and {{para|archive-date}} refer to the same snapshot.  This could mean that values assigned to either or both parameters need to be updated. To get the correct {{para|archive-date}} value, view the archived page's source, looking for a line near the bottom that starts with "FILE ARCHIVED ON". The archive date should appear on that line.
