Category.php não funciona

Boa noite, bem estou criando o tema para o wordpress do zero e estou enfrentando problemas para criar a pagina category.php, tag.php e author.php.

Ja diversos tutoriais mas nao consegui resolver, toda vez que clico para abrir as categorias, sou redirecionada para a pagina 404.php

Segue abaixo o codigo do category.php:

<?php get_header(); ?>
		<div class="pcontent">
	<?php if (have_posts()) : while(have_posts()) : the_post(); ?>
			<article class="postp">
				<div class="category">
					<span><?php the_category();?></span>
				</div>
				<!--Category-->
				<div class="agrupapost">
					<div class="ptitulo"><a href="<?php the_Permalink();?>" title="<?php the_title();?>"><h1><?php the_title(); ?></h1></a></div>
					<!--Titulo do Post-->
					<div class="infoautor">
						Por: <span><a href="<?php the_author_url(); ?>"><?php the_author() ?> </a></span> | <span class="cinzamedio">Data: <?php the_time('j/m/Y'); ?></span>
						<hr />
					</div>
					<!--Info Autor-->
						<div class="thumbpost">
						<?php
						 if(has_post_thumbnail ()) { ?>
							<a href="<?php the_Permalink();?>" title="<?php the_title();?>"><?php the_post_thumbnail(); ?></a>
						<?php } else {?>
							<a href="<?php the_Permalink();?>" title="<?php the_title();?>"><img src="<?php bloginfo( 'template_directory' ); ?>/images/388A1883.jpg" alt="<?php the_title();?>" title="<?php the_title();?>" width="auto" height="auto"> </a>
						<?php } ?>
						</div>
						<!--Thumb Post-->
						<div class="pfooter">
							<span class="pcomment">Comentarios:<?php comments_popup_link('0','1','%'); ?></span>
							<!--Comentarios-->
							<span class="leiamais"><a href="<?php the_Permalink();?>" title="<?php the_title();?>">Saiba Mais</a></span>
							<!--Continue Lendo-->
							<span class="psocial">
								<a href="#"><img src="<?php bloginfo( 'template_directory' ); ?>/images/social/pinterest.png" height="20" width="21" alt="Facebook"></a>
								<a href="#"><img src="<?php bloginfo( 'template_directory' ); ?>/images/social/facebook.png" height="20" width="21" alt="Pinterest"></a>
								<a href="#"><img src="<?php bloginfo( 'template_directory' ); ?>/images/social/twitter.png" height="20" width="20" alt="Twitter"></a>
								<a href="#"><img src="<?php bloginfo( 'template_directory' ); ?>/images/social/rss.png" height="20" width="20" alt="RSS"></a>
							</span>
							<!--Redes Sociais-->
						</div>
						<!--Footer Post-->
				</div>
				<!--Agrupa Post-->
			</article>
			<!--Article Post-->
		<?php endwhile; else: ?>
		<?php endif; ?>

			<div class="paginacao">
			<?php $npaginas = $wp_query -> max_num_pages; ?>
			<div class="npaginas">
				<span class="anterior">
					<?php
					previous_posts_link ('Anterior');
					?>
				</span>
				<span class="proximo">
					<?php
					next_posts_link ('Proximo');
					?>
				</span>

			</div>
				<p>Pagina <?php echo $paged; ?> de <?php echo $npaginas; ?></p>
			</div>
			<!--Paginação-->

<?php get_sidebar(); ?>
