I just experienced this problem with sixteen-nine. I rolled back GSS to 1.0 with success.
Finally figured out the problem. I was using a plugin to force https. But the path in the plugin settings page was picking up the path from the database (http). So all I did was force the WP path to use https and the carousel came back online 🙂

define(‘WP_SITEURL’, ‘http://example.com/wordpress’);
Here’s the link to the site in question.

I’m getting this error on the edit carousel screen.
Fatal error: Call to undefined function is_array() in /home/content/x/x/x/xxx/html/wp-content/plugins/wp-carousel/wp-carousel.php on line 2660
