Hi,

i have a working view with a simple Taxonomy Arguments, if i add a Sort criteria (Node: Post date) and push the Update Button i get a WhiteScreen.

$view = new view;
$view->name = 'culture';
$view->description = '';
$view->tag = '';
$view->view_php = '';
$view->base_table = 'node';
$view->is_cacheable = '0';
$view->api_version = 2;
$view->disabled = FALSE; /* Edit this to true to make a default view disabled initially */
$handler = $view->new_display('default', 'Defaults', 'default');
$handler->override_option('sorts', array(
'created' => array(
'order' => 'ASC',
'granularity' => 'second',
'id' => 'created',
'table' => 'node',
'field' => 'created',
'relationship' => 'none',

));
$handler->override_option('arguments', array(

));
$handler->override_option('filters', array(

));
$handler->override_option('access', array(

));
$handler->override_option('row_plugin', 'node');
$handler->override_option('row_options', array(
'teaser' => 1,

));
$handler = $view->new_display('page', 'Page', 'page');
$handler->override_option('path', 'culture');
$handler->override_option('menu', array(
'type' => 'none',
'title' => '',
'weight' => 0,
));
$handler->override_option('tab_options', array(
'type' => 'none',
'title' => '',
'weight' => 0,
));
