Why is my category.php in WP showing all posts?

Question

I am trying to configure my category.php in wordpress to show the posts which belong to a specific category.

This is the code of my category.php I'm currently using:

 <?php get_header(); ?> <div id="site-wrapper"> <main id="main"> <h2 id="category_title"><a href="#">Kategorie "<?php single_cat_title( '', true ); ?>"</a></h2> <?php // the query $args = array('posts_per_page' => -1 ); $the_query = new WP_Query( $args ); ?> <?php if ( $the_query->have_posts() ) { ?> <!-- loop --> <?php while ( $the_query->have_posts() ) { $the_query->the_post(); ?> <article id="post_cat"> <div id="thumbnail"> <?php if ( has_post_thumbnail() ) : ?> <a href="<?php the_permalink(); ?>" title="<?php the_title_attribute(); ?>"> <?php the_post_thumbnail(); ?> </a> <?php endif; ?> </div> <h2><a href="<?php the_permalink();?>"><?php the_title(); ?></a></h2> <div class="entry"> <?php the_excerpt(); ?> </div> </article> <?php } } else { ?> <p><?php _e( 'Die Posts entsprechen nicht den Kriterien.' ); ?></p> <?php } ?> <!-- end of the loop --> <?php wp_reset_postdata(); ?> </main> <?php get_sidebar(); ?> <?php get_footer(); ?> 

The code looks good but the problem is that all of the posts which are in index.php are displayed.

I hope that someone could help me! Thanks in advance!

Remove the custom query, that is your issue. Your loop should look something like this:

while ( have_posts() ) :
    the_post();

        // The rest of your loop code

endwhile;
