I just noticed that when I use featured images on my blog posts that they are not aligning properly with the post, but rather are moved over to the left and align with the date (so the date appears on top of my image.)
This does not seem to happen with pictures that are in the actual blog post, just the featured images.
Thanks for the screenshot. I see the problem on your site now. When I visit http://hundredgoals.com/page/3/, I notice that there are ads loading on that page. I suspect that might be causing the problem. I will report this to our team, and will get back to you as soon as I have more information. Thank you for your patience!
