Can't see individual blog posts

I am using parabola. I have a blog page on my website. I have posted two posts. They both show up when I click the navigation button for the blog (barkin’ and yappin’) but when I click on the individual post within the blog page I don’t see the individual post. I get this message instead Not Found
Apologies, but the page you requested could not be found. Perhaps searching will help.

I’ve searched your forums but can’t find the answer.
