Single post pages not showing and comment link not working

[pickle_jar]

I'm in the processes of migrating my website and blog all into this theme: http://www.picklejarcommunications.com

I have a blog page and have imported all blog posts from my blogger blog. I have also created a new blog post directly on here since completing the migration to check it's all working. No problems with creating a new blog post.

However, I have noticed a couple of things:

Firstly, when I'm on the blog page (/blog), the link to each blog post (ie for the single post page) is not working - instead, when I hover on the title I just get the same url:
http://www.picklejarcommunications.com/ ... s.com/blog

Secondly, the comment link is not working. When I hover on this it shows:
http://www.picklejarcommunications.com/ ... og#respond
This doesn't take you to a comments page.

Any thoughts? I think others have found similar issues, but I've tried some of the solutions to problems that sounded similar and it isn't working. Thanks in advance for any suggestions!
