Like Box Not Showing Right Border

Hello, I just installed WP and I am in the process of getting it set up and configured. I installed the FB social media plugin. The like box doesn’t show the right border. I have played with CSS with no luck and can’t get it to show at all. Is there some special trick I don’t know about? I don’t know if this is a WP CSS issue or related to the plugin but, they told me to post over here so that’s what I am doing.

Here is the page. It is at the bottom on the left sidebar.

Here is another page using the exact same plugin and template and theirs shows just fine.
