Has anyone else seen this error under Joomla and CiviCRM 5.10.4 when viewing a contact via the front end?

Warning: hash_equals(): Expected user_string to be a string, null given in /.../administrator/components/com_civicrm/civicrm/CRM/Contact/BAO/Contact/Utils.php on line 232

  • Are you viewing the contact via a link that has "cs=" in the url? – Demerit Mar 5 at 15:51
  • Not that I am aware. $inputCheck is null when validChecksum is called, CRM_Utils_Request::retrieve('cs', 'String', $form, FALSE) returns a null value. – Stephen Palmstrom Mar 6 at 13:05
  • I'm having the same issue after upgrading to CiviCRM 5.13.12 – user1314302 May 7 at 18:58
