I want to change my category list in my list of post, and single post from “,” to ” “. I have already implement this code in functions.php

function custom_category_list_separator($list) { $new_separator = ‘|’; // Replace ‘|’ with your desired separator $list = str_replace(‘,’, $new_separator, $list); return $list; } add_filter(‘the_category’, ‘custom_category_list_separator’);

But it still didn’t work. I think it maybe different filter that this theme call for category instead of “the_category”. I have already read the docs, and still couldn’t find any info. Please help.
