Display latest post from a certain category on a “page”

Here’s the page in question: https://www.framsidan.net/senaste-numret/
To somehow have that static url display the latest post from a category…

if you have not already, read the information of the codex:

https://codex.www.ads-software.com/Pages
https://codex.www.ads-software.com/Pages#Page_Templates

make a page template, by following the instructions, (as a start, you could use the code from page.php or single.php, and then customize it to your needs)

and then add a query for your certain category before of the loop.

https://codex.www.ads-software.com/Template_Tags/query_posts#Category_Parameters

and then in admin/ pages/ edit/ edit the page ( used to show the “latest issue”) and the choose your new page template under ‘attributes’ ‘template’ from the drop-down list.

Thank you! Very helpful. I’ll try this.

I think I get it, but unfortunately I suck at PHP. Maybe you could help out with what I need to change here to make this code display the latest post from a category. This is the code from single.php in arras-theme which I use:

<div id="content" class="section">
<?php arras_above_content() ?>

<?php
if ( arras_get_option('single_meta_pos') == 'bottom' ) add_filter('arras_postfooter', 'arras_postmeta');
else add_filter('arras_postheader', 'arras_postmeta');
?>

<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
	<?php arras_above_post() ?>
	<div id="post-<?php the_ID() ?>" <?php arras_single_post_class() ?>>

        <?php arras_postheader() ?>

        <div class="entry-content">
		<?php the_content( __('<p>Read the rest of this entry &raquo;</p>', 'arras') ); ?>
        <?php wp_link_pages(array('before' => __('<p><strong>Pages:</strong> ', 'arras'),
			'after' => '</p>', 'next_or_number' => 'number')); ?>
		</div>

        <!-- <?php trackback_rdf() ?> -->
		<?php arras_postfooter() ?>
    </div>

	<?php arras_below_post() ?>
	<a name="comments"></a>
    <?php comments_template('', true); ?>
	<?php arras_below_comments() ?>

<?php endwhile; else: ?>

<?php arras_post_notfound() ?>
<?php endif; ?>
<?php arras_below_content() ?>
</div><!-- #content -->

So far I added:

<?php query_posts('category_name=tidningen&posts_per_page=1');

And it does what I want, however, it doesn’t display the comments below the post!
