ARCHIVE.PHP SHOWS ONLY ONE POST PER CATEGORY - php

Question

I realized my website (www.inunfuturoaprile.it) with a minimal Wordpress theme that does not include the category.php template. I have created the template by me: the goal was to get pages that display a list of the posts belonging to a specific category. Unfortunately, due to my scarce knowledge of php, the code does not seem to work properly: I only see one post per category (e.g. https://www.inunfuturoaprile.it/politica/).
Here's the category.php file code:
<?php
/**
* Template di Categoria
*/
get_header(); ?>
<div id="content">
<?php
// Check if there are any posts to display
if ( have_posts() ) : ?>
<?php
// Since this template will only be used for Design category
// we can add category title and description manually.
// or even add images or change the layout
?>
<h1><strong><?php single_cat_title(); ?></strong>: Elenco Articoli</h1>
<div class="entry">
<?php
// The Loop
while ( have_posts() ) : the_post(); ?>
<?php the_title(); ?> // <small><?php the_time('j F Y') ?></small>
<?php endwhile; // End Loop
else: ?>
<h2 class="center">Not Found</h2>
<p class="center">Sorry, but you are looking for something that isn't here.</p>
<?php endif; ?>
</div>
</div>
<?php get_footer(); ?>
Someone can help me? Thank you :)

I think your posts_per_page parameter is set to 1.
You can see other posts using pagination:
https://www.inunfuturoaprile.it/politica/page/2/
https://www.inunfuturoaprile.it/politica/page/3/
Check it on Settings->Reading page ( /wp-admin/options-reading.php), parameter "Blog pages show at most"
But it also can be set up somewhere in the theme code.
Changing it may affect your main page - since the main page shows only one post too.
So you can change it only on category.php page. Add this after get_header():
get_header();
global $wp_query;
$wp_query->set('posts_per_page', 10);
// or this - if you need no pagination at all:
// $wp_query->set('nopaging', true);
$wp_query->query($wp_query->query_vars); ?>
