wall of text on blogs

All the posts on my site, not the pages, have turned into a continous wall of tekst.

When I edit my posts, I am able to put the tekst into blogs, so each topic on the post is separated. But when i submit it to public view, all the words just becomes as a massive wall of text. There is new lines.

Does anyone know how to change this?
