Views Not displaying properly

I upgraded both drupal and views from about a year ago and now views is not displaying a page I had setup. I also did clear cache as instructed. I had a page that was based on taxonomy. It used to show the taxonomy items as links (for a taxonomy vocabulary Tech Info I would have 3 items, Bodywork, drivetrain and Engine), then if you clicked one of the links (for Bodywork, drivetrain and Engine) it would show the node title for each node and summery with that taxonomy assigned. But now I get the links for taxonomy items but once clicked nothing. Also, the links show the correct number of items that are assigned the taxonomy name. Below is a link to the page:

Here is an export of the view:

$view = new view;
$view->name = 'Tech_View';
$view->description = '';
$view->tag = '';
$view->view_php = '';
$view->base_table = 'node';

$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');

I would be very grateful for any help!
