[GET][NULLED] - Really Simple SSL Pro 6.1.0

Is anyone else experiencing errors after enabling this plugin?
Six lines of errors similar to the one below.

Example:

Quote: information - headers already sent by (output started at /home/XXXXXX/public_html/XXXXXX.com/wp-content/plugins/really-simple-ssl-pro/settings/sync-settings.php:64) in /home/XXXXXX/public_html/XXXXXX.com/wp-includes/option.php on line 1138

Thanx
