Issue with Pay With A Like plugin

Hi there - I"m having some trouble getting Pay With A Like to work properly on this page: http://girlsguidetowebdesign.com/course/bonus-video-content/

The buttons show up fine, and when clicked, I get a small window that appears and then quickly closes. Then the page refreshes, but the video content that is meant to show at the bottom of the page doesn't show up.

I put the video content between the two shortcodes, like this:

<h3>Video 1:</h3>
<iframe src="https://player.vimeo.com/video/121492575" width="800" height="600" frameborder="0" allowfullscreen="allowfullscreen"></iframe>
<h3>Video 2:</h3>
<iframe src="https://player.vimeo.com/video/121492916" width="800" height="600" frameborder="0" allowfullscreen="allowfullscreen"></iframe>
<h3>Video 3:</h3>
<iframe src="https://player.vimeo.com/video/121493223" width="800" height="600" frameborder="0" allowfullscreen="allowfullscreen"></iframe>
<h3>Video 4:</h3>
<iframe src="https://player.vimeo.com/video/121493421" width="800" height="600" frameborder="0" allowfullscreen="allowfullscreen"></iframe>
<h3>Video 5:</h3>
<iframe src="https://player.vimeo.com/video/121493568" width="800" height="600" frameborder="0" allowfullscreen="allowfullscreen"></iframe>

Is this the right way to do it? Any idea why the content isn't showing after a share/tweet/like, or why the weird popup appears and then vanishes?

Thanks!
