The categories and comments of a post are placed under my post title. The category must link to the category page and the comments must link to the comments page. I use <?php the_category(', ') ?> to display the category of a post and <?php comments_popup_link('Geen reacties', '1 reactie', '% reacties'); ?> to display the comments.
It works fine but not for the first post on a page, the second and third are working. Same thing for the title of the last post under "Recente artikelen" in the sidebar.
You can see it yourself at http://www.nextfacts.nl. Does someone know how this could happen?
