I’ve disabled all plug-ins and it’s still an issue. Comment-wise, the template seems to be barebones.
Here is the code from my comments.php file

I can’t find anything related to comment_author_link
I’d mess around with it, but unfortunately I don’t know php.
It took me a while, but I figured it out. Facebook, Twitter, and Google+ each have meta data they require in order to pull the correct data from your blog.
Here’s how to get it working on each social media site (note, the data required differs across social media sites)

junglegeek, the CSS on your page is a bit different than mine. I checked out your site and this fix worked for yours, so you might want to give it a shot:
element.style {
height: 5px;
}
