Same content, other appearance!
The wordpress theme JS O3 lite didn't work anymore, maybe because of some plugin updates. I don't have much time to fix it or search a new, so I choosed the journalist theme that looks simple and nice. It's a little bit technical and not as elegant as the old theme, so maybe I will continue my search for the beste theme in the future.
I had to replace the_content with the_excerpt in some files to let the index pages show summaries only.
