Note that the value of PHP's configuration option magic_quotes_gpc is incorrect. It should be set to '0' for Drupal to work properly. Either configure your webserver to support .htaccess files so Drupal's .htaccess file can set it to the proper value, or edit your php.ini file directly. This message will automatically dissapear when the problem has been fixed.
