Page in a category?

Pages doesn’t get categories. It’s showing up as “Uncategorized” because that’s your default category and because you have the template tag to display the category in your theme’s Page layout.

If you have a single.php in your theme’s directory, make a copy of it and name it page.php. Then delete all of the category part out of it.

If you only have an index.php, then try something like this:

<?php if (!is_page()) { the_category(); } ?>
