[Theme: Cleanr] h2 css being overruled

I’ve recently made changes to the fonts on my wordpress page, and now I can’t figure out how to do it again. We recently transferred the page from one url to another, and I’m wondering if the css from the old url is somehow overruling the new style.css page. I’m basically trying to change the font on my h2. When looking at the html in Firebug or a similar html-in-browser viewer, the old font is overruling the new, and I can’t figure out where it is coming from. All references to this old font are gone from every css file under the theme. Is this possibly coming from another stylesheet, either on our main site or otherwise?

Thanks.
