[Plugin: Feed2Post] Link to post is broken

I have feed2post pulling in Google+ posts. They are showing up in my blog, but the permalinks to each post don’t work. See http://www.cockingfamily.com to see what I’m talking about. The post at the top of the blog (“Chiang Mai diary”) was imported from G+. But click on the title of the post and you get a 404.

How can I fix this so the posts have working permalinks?
