When someone registers for an event, it now registers them but crashes on to an error page, stating that "source_contact_id is not a valid integer".
I think this has been happening since Civi 5.0.1
I am using Civi 5.0.2 and Drupal 7.59
The Fatal Error Page from the error log is very long, but here's the first bit:
$Fatal Error Details = array(3) { ["message"]=> string(40) "source_contact_id is not a valid integer" ["code"]=> NULL ["exception"]=> object(CiviCRM_API3_Exception)#420 (8) { ["extraParams":"CiviCRM_API3_Exception":private]=> array(3) { ["is_error"]=> int(1) ["error_message"]=> string(40) "source_contact_id is not a valid integer" ["error_code"]=> string(9) "undefined" } ["message":protected]=> string(40) "source_contact_id is not a valid integer" ["string":"Exception":private]=> string(0) "" ["code":protected]=> int(0) ["file":protected]=> string(88)
Anyone else having this problem or have any ideas?
