Widget Titles Missing

Hi, I’m using theme Elegante and all of the sudden the titles for my widgets on the right sidebar have disappeared. I contacted the creators and they recommended using Cufon font replacement because the theme was built using sIFR, which is outdated. I’ve gone through the Cufon steps, but it only seems to work on the main content, not the widgets on the sidebar. Any ideas? Thanks!
