I think this is caused by the blog url being: "blog_url": "http://cakespirit.co.uk/Recipes", and the "url_prefix": "blog"
I think the thing to try is setting the url_prefix to "Recipes" in the config.php and admin settings.
Plugged in a fix for the tracker bug in the logs:

This will be out in the next Pulse update
