What theme are you running?
Are you referring to Pages or Posts because they are two different types or rather, what we call Post Types.
- Pages are normally controlled via your
page.php
template file - Posts are normally controlled via your
single.php
template file
Commonly you will find category and tag functions in your single.php
file, but calls to such functions are not strictly limited to a single.php
file. They can in fact be used in multiple theme files.
So for example,
- if you are viewing a Single Post, then look within
single.php
- if you are viewing a list of your Posts, then look within
archive.php
You will be looking for template tags such as,
<?php the_category(); ?>
or...
<?php the_tags(); ?>
