iCoach Hero widget not visible on frontpage

I’ve build my website with the iCoach theme from Indigothemes.
On the homepage of my website the large header that is defined by the iCoach Hero widget is not visible anymore.
We used a suggestion from an other thread saying that you should turn off the “use fittext”, that worked, in the sense that the content of the Hero widget is now visible, but the site is not fully responsive anymore.
It would be great if anyone can help me to solve this issue.
