Notice: wpdb::escape is deprecated since version 3.6! Use wpdb::prepare() or esc_sql() instead. in /Users/emmanouilgketsim/htdocs/svn/infosource.culturalcare.com/wp-includes/functions.php on line 3078
For WP version >= 3.6, use esc_sql() instead of $wpdb->escape and it should not throw any notice.
Thanks for it
For WP version >= 3.6 use in line 12
$meta = $wpdb->get_results( $wpdb->prepare( "SELECT * FROM ".$wpdb->postmeta."
WHERE meta_key=%s AND meta_value=%s", $key, $value ) );
