Missing styling on user pages

Some pages on the user pages are missing styling. For example;

https://blog.torproject.org/users/arma (see latest (top) post). https://blog.torproject.org/users/arma?page=1 (all posts). https://blog.torproject.org/users/gk?page=1 (all posts).

However, not all pages all like this. For example;

https://blog.torproject.org/users/arma?page=2 https://blog.torproject.org/users/gk?page=2
