Answers.Text: Excellent - glad that helped you out. Next time I’m in the section I’ll have a look and check why we have that notice (and fix it) but the answer still is you never want to show notices and errors to your website visitors.

Body: <p>When my Drupal CiviCRM Webform is filled out and submitted, the CiviCRM database appears to be updated correctly. That is, a new contact is created with all the proper information included from the form. The Webform confirmation page announces: "Thank you, your submission has been received."

  <p>"Warning: implode(): Invalid arguments passed in CRM_Core_BAO_CustomGroup::postProcess() (line 1551 of /home/mywebsite/www/crm/sites/all/modules/civicrm/CRM/Core/BAO/CustomGroup.php)."</p>
  
  <p>Any idea what this means and how to get rid of the error message?</p>
