Kann kein neues Album erstellen

Hallo,
ich kann in meiner Galerie (3.0.4) leider kein neues Album erstellen.
Ich bin eingeloggt als Admin und es kommt immer folgende Fehlermeldung:

ORM_Validation_Exception [ Database Error ]:
ORM Validation has failed for items model
SYSPATH/libraries/ORM_Validation_Exception.php[ 20 ]

15 * @param Validation $array
16 * @return

18 public static function handle_validation($table, Validation $array)
19 {
20 $exception = new ORM_Validation_Exception('ORM Validation has failed for :table model',array(':table'=>$table));
21 $exception->validation = $array;
22 throw $exception;
23 }
24} // End ORM_Validation_Exception
