post fully opened when clicked category

a link to your blog would help ??

the template-tag to show the whole post is:
<?php the_content(); ?>

the template-tag to show the excerpt is:
<?php the_excerpt(); ?>

the template-tag to show the title is:
<?php the_title(); ?>

if there’s a file archive.php in your template directory, you’ll find the above title-tag in this file. to show the whole post you have to add the “content-tag” right after the title-tag.

for example:

<div class="bla">
<h1><?php the_title(); ?></h1>
<?php the_content(); ?>
</div>

if your archive page (the page with posts from only one category, date, etc.) looks the same as your index page, you can copy this from your index.php.

yes, that works for me. Is there an option to add the comments too?

for example: https://fanste.nl/?cat=21 you see it says 3 comments at the post “dude” but i can’t see the 3 comments????

on https://fanste.nl/?p=625 i can see the 3 comments, but i want to see at the archive too. not only at a single post.
