Problem creating a portfolio overview page. I've followed the method of making a portfolio exactly, but there is a problem with youtube videos. The single item video pages show correctly, but when I load the portfolio overview page, nothing loads, just the loader image. Firebug reports this problem on the scripts console:
JSON.parse: bad control character in string literal
If I load the dummy content all works correctly, including the portfolio overview page. On your demo site this URL is the page that fails on my test site http://www.kriesi.at/themes/sentence/portfolio-3-columns/ PLease advise.
