Hello, this is the code I'm using:

self::$DB->prepare($query, $types);

when the $query and types are:

//$query
UPDATE Permisos
    SET                 
        empleado_id = ?,
        agregar_mensaje = ?,
        borrar_mensaje = ?,
        agregar_noticia = ?,
        borrar_noticia = ?,
        agregar_documento = ?,
        borrar_documento = ?,
        agregar_usuario = ?,
        borrar_usuario = ?,
        agregar_empresa = ?,
        borrar_empresa = ?,
        agregar_tarea = ?
    WHERE
        id = ?
//$types
Array(
    [0] => integer
    [1] => boolean
    [2] => boolean
    [3] => boolean
    [4] => boolean
    [5] => boolean
    [6] => boolean
    [7] => boolean
    [8] => boolean
    [9] => boolean
    [10] => boolean
    [11] => boolean
    [12] => integer
)

Everything works great, but when they are:

//$query
UPDATE Permisos SET                         
         empleado_id = ?,
         agregar_mensaje = ?,
         borrar_mensaje = ?,
         agregar_noticia = ?,
         borrar_noticia = ?,
         agregar_documento = ?,
         borrar_documento = ?,
         agregar_usuario = ?,
         borrar_usuario = ?,
         agregar_empresa = ?,
         borrar_empresa = ?,
         agregar_tarea = ?,
         borrar_tarea = ?
    WHERE
id = ?
//$types
Array(
        [0] => integer
        [1] => boolean
        [2] => boolean
        [3] => boolean
        [4] => boolean
        [5] => boolean
        [6] => boolean
        [7] => boolean
        [8] => boolean
        [9] => boolean
        [10] => boolean
        [11] => boolean
        [12] => boolean
        [13] => integer
    )

It fails with the following message:

<b>Warning</b>:  PDO::prepare() [<a href='pdo.prepare'>pdo.prepare</a>]: SQLSTATE[HY000]: General error: PDO::ATTR_STATEMENT_CLASS requires format array(classname, array(ctor_args)); the classname must be a string specifying an existing class in <b>C:\wamp\www\intratin\JP\includes\empleado\mapper\Permiso.php</b> on line <b>137</b><br />

Doesn't matter which field I add or remove, it fails every time with more than 13 placeholders.
