Body Font Settings Are Not Working

Hi, I have Google Web Fonts enabled for the body text of my articles. However, when I change the size of the font on the backend of the site, nothing changes on the front end. Even when I test it by making the font exorbitantly large, it still remains tiny on the front end. What can I do to make the body font larger? Something is clearly wrong and I don’t know what to do to fix this issue.

Thanks
