CiviCRM Community Forums (archive)

We have had a particular contact for many versions of civiCRM.

For the first time they have registered for an event (as an anonymous drupal user) - their first name is 'Sam' or 'Samantha' and whilst we have always used their personal email they have recently been appointed to a new body and have a very smart new email.

Consequently the registration created a new crm contact record.

On merging the two records later the following error message was displayed:

Sorry. A non-recoverable error has occurred.

One of parameters (value: 0) is not of the type Timestamp

The merge and delete appear to have been successful and correct.
