I've just istalled this on a new blog and set up a feed - http://legjoints.com/feed/ - but on trying to process this I get an error saying no posts in your feed(s) and then trying test import I get:
Feed Testing Results
Error: WP HTTP Error: couldn't connect to host
It's set up to import all posts and force ssl verification is set to no. There are posts in the feed and the validator confirms it is valid.
