    If warnings are enabled in PHP, then you will get:

    Login to http://example.com

    Warning: Cannot modify header information – headers already sent by (output started at /home/username/www/example.com/public_html/wp-content/plugins/social-connect/google-plus/connect.php:9) in /home/username/www/example.com/public_html/wp-includes/pluggable.php on line 1172

    Shouldn’t line 9 in connect.php be:
    $app_name = sprintf(...);
    instead of:
    $app_name = printf(...);
