Wrong parameters for Exception([string $exception etc error

I am having issues with a client website where hummingbird will not launch. and throws an error

Fatal error: Wrong parameters for Exception([string $exception [, long $code ]]) in /home/content/e/h/o/ehodgesgodaddy/html/aec/wp-content/plugins/wp-hummingbird/core/api/class-wp-hummingbird-api-exception.php on line 19

I'm hosted on GoDaddy but other 2 websites are running Hummingbird ok.
