missing content on index for my latest genodians.org post

Hello Genodians

I pushed a new article to my genodian repository (github.com/trimpim/genodian. On the index page no content is displayed. This didn't occur to me while writing, as I always directly looked at the page I edited.

I already tried to figure out, what is wrong, so I could push a fixup. I compared the new article to the old one and the title and the first paragraph are formatted about the same.

Could anyone give me a hint what could be wrong with my article?

Best regards, Pirmin
