Panino: Getting Fatal ERROR on Blog Posts in theme files, how do I correct this?

Hi Support,

I am getting a fatal error when I click on any of the blog posts for the site, http://gambrillsfitnessstudio.com/blog

I will attach a screenshot to show you what error I'm getting.

I just got off the phone with my hosting and server support folks and they did some diagnostic tests and from what they can see it looks like there is an update that I need to do on my theme files. I have updated everything but I'm still getting the error.

Can you help me with this?
