Filters not working

Last night I upgraded from 6.x-3.0-alpha2 to 6.x-3.0-alpha3,

Update process went alright no errors where displayed, however, all my views where broken, all the custom outputs where broken. with plain text rather than views display.

I could not add any filter, header, footer or any text or argument to the views even after selecting header global text, nothing was displayed.

Reverted back to 6.x-3.0-alpha2 views display normally...

So decided to go to 6.x-2.10 version as it was stable.

Now I can't apply any filter. Even when applying filter all the values are display..

Did a fresh install of Drupal 6.16 installed views and made the view from scratch DID NOT IMPORT..again filters not working.

Attached is the copy of the view:

$view = new view;
$view->name = 'user_stats_online_users_pictures';
$view->description = 'Shows who is online by displaying their user pictures (avatars).';
$view->tag = '';
$view->view_php = '';
$view->base_table = 'users';
$view->is_cacheable = FALSE;
$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('fields', array(
  'uid' => array(
    'id' => 'uid',
    'table' => 'users',
