It doesn't work at all

Same here. Using /%custom_taxonomy_slug%/%postname%/. Right URL, but 404.

Same here. The link urls are good, but when clicked, the expected page does not show up.

Me too 404!

Same issue here. 404’s … oddly enough some links fall through to a similar url with a different sublevel. (i.e. I set up a structure for “/donate” and /donate/event-name-1 will somehow redirect to /event/event-name-1 if it exists)

BTW, I inserted this into the functions.php file and it’s working now:

function my_custom_add_rewrite_rules( $wp_rewrite )
{
	$new_rules = array(
		'donate/(.+?)/?$' => 'index.php?ch_cause=$matches[1]',
	);

	$wp_rewrite->rules = $new_rules + $wp_rewrite->rules;
}
add_action('generate_rewrite_rules', 'my_custom_add_rewrite_rules');

Replace “ch_cause” with your post type and “donate” with the folder structure you want.

Not great but at least a work around.
