Why is this Twitter API script not working?

Question

I get an error from this Twitter script, which is why the rest of the page does not load. Not sure why this happens all of a sudden, where it functions properly for some time.

The script looks like this and it gains the current status of the user:

<?php  
$response = new SimpleXMLElement('http://twitter.com/users/show/tuscaroratackle.xml',NULL,TRUE);  
echo $response->status->text.'';  
?>

Here is another post in which I tried to figure out the answer to another error that pointed me to this error on Twitter.

You can see here in the footer or screengrab output: http://cl.ly/33IZ .
