only one column

Hi,

I’ve been desperately needing to update my theme for months and months and Baskerville looks to fit my needs perfectly. a 3-column responsive, mobile friendly, elegant and much cleaner theme than I currently have.

However, when I preview it everything is in one column:-

It seems the absolute positioning isn’t being set for the “post-container” elements. Can anyone see what is wrong with my site that’s causing this? Some conflicting plugin is my thought.

Thanks.
