When I try to archive an existing story then there is an error message:

user warning: Incorrect integer value: '' for column 'created_on' at row 1 query: INSERT INTO archiver (nid, created_on) VALUES ('3', '') in C:\WEBDEV\websites\drupal\includes\database.mysql.inc on line 172.

However, I can archive a story when I open it and change its property directly.

I installed it for the latest Drupal 5.2

Thank you.
