Strict Standards error notice

There is a Strict Standards: call_user_func_array() expects parameter 1 to be a valid callback, non-static method Adobe_Analytics::init() should not be called statically in /Users/jpresley/Sites/wordpressunified/httpdocs/wp-includes/plugin.php on line 429 notice. This can be fixed by either changing the lines add_action('init', array('Adobe_Analytics', 'init')); add_action( 'wp_print_footer_scripts', array('Adobe_Analytics', 'script'), 50 ); to add_action('init', array(&$adobe_analytics, 'init')); add_action( 'wp_print_footer_scripts', array( &$adobe_analytics, 'script'), 50 ); adobe_analytics.php. Alternatively you can change the definitions of ‘script’ and ‘init’ methods to public static function. https://wordpress.org/plugins/adobe-analytics/ Passing the object by reference would be incorrect. Just omit the ampersand before the $adobe_analytics object.
