Jetpack Like button loading forever

Hello, I’m new to ww.wp.xz.cn and not that familiar with the terminology. I’m having a problem with the Jetpack Like button not loading. I just get grey “loading” instead of the Like button. I’ve stopped enabling it on the last few posts at http://YummyLummy.com because readers commented they couldn’t Like the post. I’ve enabled for the last post at http://yummylummy.com/food/monster-expectations/ in the hope that someone here can help me with the answer. I’m using the latest version of ww.wp.xz.cn and Jetpack plug in. I’m using the Portfolio+ theme. Thanks for your help.
