我能想到兩個主要原因。

1. The person doing the editing was doing it whilst logged in as the other person. Possible scenarios and suggested 'solutions' are:

   • shared computers where the other person didn't log out when they had finished and the editor didn't bother to sign in as themselves. Solution: Remind all concerned of the importance of logging out when finished and of using their own log in.
   • The editor is able to masquerade as the other person and was doing so when making the changes Solution: Remind editor that they should not make changes whilst masquerading as someone else OR revoke their masquerade priviledges.
   • The editor knows the password of the other person and deliberately logged in as that user. Solution: Get the other person to change their password and keep it private.

2. The table that links wordpress user to civicrm contact record has become (or was for a while) corrupted so that the wordpress login for the editor is/was linked to the civicrm record for the other person. (This could happen for a drupal-based site if the uf_match table was corrupted. I presume there is something similar in wordpress, but I don't really know.)
