A dedupe rule using birth date is not working with drupal CMS. I receive the message "unknown error, please contact your administrator". The rule is working well in WordPress

  • In our installation with Drupal it is not working. Maybe it depends on the version. We use the 5.9.1

This sounds odd since it should not be CMS related. I tested on dmaster - set up a DoB based rule, it worked

Link is below but will be removed when site next rebuilds in a few hours


Is it possible you made an error setting up your Rule?
