PHP-Error

Hello,

just another question.

I get regulary the following error-notice:

PHP Warning:  Undefined array key "host" in /homepages/uXXXXX/wpX/wp-content/plugins/wp-slimstat/wp-slimstat.php on line 225

whereas line 224-226 have this code:

// .. or outbound link? If so, update the pageview with the new info
else if ( $parsed_resource[ 'host' ] != $site_host ) {
self::$stat[ 'outbound_resource' ] = $resource;

Please, could anybody help?

Thank you and kind regards
