Portfolios are not displaying

Hi,
I am working on a website, productionsspectrum.com, and all of a sudden, my portfolios no longer work. Where there used to be a portfolio in the page, I get a white space with no error code, nothing. I think it might have happened when I tried to duplicate the portfolios to produce a French version and a English version for PolyLang. Any ideas on how to fix this?

Thanks a lot,
