Twitter Embed not working

Hi Alex,

Loving your theme and the support you’re providing. I have a bit of trouble posting tweets. I just put the tweet URL like I would on other wordpress websites but for some reason the iframe shows up as 0px. It’s just left with a line and a really big space.

Here’s my sample : http://malaysiangeek.com/2014/09/12/worldwide-iphone-6-preorder-fiasco/

Could you help me out? Thanks.
