Error message SQLSTATE[HY093]: Invalid parameter number: number of

Could someone give me any advice?
The error has to do with a bug related to User: Representative node. Checkout https://www.drupal.org/node/1417090. Comment #35 has a patch for the latest dev version of views that will possibly fix the issue.
