[Resolved] Post Category Not Showing

It would be best to reverse any customisations you’ve made. If you aren’t quite sure then you can go to Appearance > Themes, switch to any other theme, delete Polestar and then reinstall and reactivate Polestar, that’ll restore the theme files to their original state. If you’ve customised other files in other tasks then let me know as you need to move those to a safe place before restoring.

Next, go to Plugins > Add New, search for and install a plugin called Code Snippets.
Go to Snippets > Add New and create a new snippet. Name it as you’d like.
In the snippet body, insert:

if ( ! function_exists( 'polestar_post_meta' ) ) :
/**
 * Print HTML with meta information for the sticky status, current post-date/time, author, comment count and post categories.
 */
function polestar_post_meta() {
	if ( ( is_home() || is_archive() || is_search() ) && get_theme_mod( 'post_date', true ) ) {
		echo '<span class="entry-date"><a href="' . esc_url( get_permalink() ) . '" rel="bookmark"><time class="published" datetime="' . esc_attr( get_the_date( 'c' ) ) . '">' . esc_html( get_the_date( apply_filters( 'polestar_date_format', 'F d, Y' ) ) ) . '</time><time class="updated" datetime="' . esc_attr( get_the_modified_date( 'c' ) ) . '">' . esc_html( get_the_modified_date() ) . '</time></span></a>';
	}

	if ( is_single() && get_theme_mod( 'post_date', true ) ) {
		echo '<span class="entry-date"><time class="published" datetime="' . esc_attr( get_the_date( 'c' ) ) . '">' . esc_html( get_the_date( apply_filters( 'polestar_date_format', 'F d, Y' ) ) ) . '</time><time class="updated" datetime="' . esc_attr( get_the_modified_date( 'c' ) ) . '">' . esc_html( get_the_modified_date() ) . '</time></span>';
	}

	if ( get_theme_mod( 'post_author', true ) ) {
		echo '<span class="byline"><span class="author vcard"><a class="url fn n" href="' . esc_url( get_author_posts_url( get_the_author_meta( 'ID' ) ) ) . '" rel="author">' . esc_html( get_the_author() ) . '</a></span></span>';
	}
	
	if ( comments_open() && get_theme_mod( 'post_comment_count', true ) ) { 
		echo '<span class="comments-link">';
  		comments_popup_link( esc_html__( 'Leave a comment', 'polestar' ), esc_html__( 'One Comment', 'polestar' ), esc_html__( '% Comments', 'polestar' ) );
  		echo '</span>';
	}
  
	if ( has_category() ) {
		echo '<span class="cat-links">' . get_the_category_list( esc_html__( ', ', 'polestar' ) ) . '</span>';
	}  
}
endif;

Below the snippet body enable the setting that only runs the snippet on the site front end. Finally, click Save changes and activate. Note that you can save without activating (common mistake) so you need to save and activate.

Super 🙂 Glad to hear that did the trick.

If you’d be prepared to reactivate categories and let me check the issue live for a minute, that would be most appreciated. What browser are you using?

The categories displaying now, is that from your original edit of the theme function? When I tested the snippet I sent it was styled, your categories at the moment, aren’t.

(It might be worth turning off the sticky header for this site. The size of the logo means that there isn’t much screen real estate left on a laptop screen when the header is sticky.)
