What does it mean if my drupal works after I have run update.php, but then starts showing 'Internet Explorer cannot connect' after about an hour or so, with the following error message:

PHP Fatal error: Call to undefined function filter_xss_bad_protocol() in /user/htdocs/includes/common.inc on line 850

Please help!
