I ended up working this out…
I needed to change get_featured_posts in featured-content.php to query using get_pages.
After I did this, the featured-pages appeared as expected and required a little fine-tuning in content-featured-post.php to display they way I wanted them to.
Same problem here, in my case I updated the plugin manually (as I’m using AppFog to host).
HTTP 500 when I try to run an existing job and blank settings screen.
Creating a new job doesn’t help, same behaviour as above.
