Post Titles not showing up

I just noticed today that on a site that I admin, the titles for posts are not showing, however, when I review the page source in the browser, it does show the title information in it’s proper location, within the html. Furthermore, when I view the “inspect element” using Chrome, it’s shows some of the css information with a strikethrough and I don’t understand why.

Can someone take a look at the following page and help me to get the post titles to show again?
