Projects from a Category don't show content

[billyben]

Since a couple of days my Website has issues displaying Project content.
Example of one of these pages: http://www.sommerakademie-paul-klee.ch/neu/

What is wrong with it? Does anyone have an idea? I am no code-pro, so please ;) keep it simple :)

Looking forward to hearing from anyone!

Hi billyben,
what exactly is the problem? I can see text and images on the page.

Many wishes!
