Next and prev. links are broken with different blog url

I have WordPress running as a complete CMS at https://www.gourmetbryggeriet.dk/ and it’s working like a charm so far.

I have run into a small problem though. As soon as the blog got enough entries to generate next and prev. links, I could see that the links weren’t working.

I am running a different template for the blog (which is not located at the frontpage), it’s called blog.php and looks like this:

<?php
/*
Template Name: Blog
*/
?>
<?php get_header(); if (have_posts()) : while (have_posts()) : the_post(); ?>
<h2><?php the_title(); ?></h2>
<?php endwhile; endif; ?>
<?php query_posts(‘cat=-0’); //gets all posts
?>

And then the loop. But what could be wrong since the links are dead?

Scroll to the bottom to notice that the links are not working.
