I use Easy Fancy Box on a few other website and haven't had a problem until now. I have a site with a custom designed/programmed wordpress theme and I can't get iFrames to work. Here is the code I'm using:
Instead of the pdf showing up in an iFrame, it automatically opens a new page with the pdf in a google viewer. Check out the page here, the link is under BookmarkTrendz "View the 2012 catalog"
Any help is appreciated! Thanks!
