Search Engine Optimization

Tell me how to make for categories (headings) a URL with "/" at the end, while leaving the entries without "/"?

Answer 1

Try adding in to functions.php file

function pcl_smart_trailingslashit($string) {
  /* ensure, that there is one trailing slash */
  $string = rtrim($string, '/') . '/';
  /* if there is a filename extension like .html or .php, then remove the trailing slash */
  if ( 0 < preg_match("#\.[^/]+/$#", $string) ) {
    $string = rtrim($string, '/');
  }
  return $string;
}
add_filter('user_trailingslashit', 'pcl_smart_trailingslashit');

and in the CNC settings, set "Arbitrary", add /% postname%
