%monthnum2% cannot be read

Hi @helentacang,

This tag is not included neither in Permalink Manager nor WordPress core codebase.

Actually, I have found that this tag (with a custom code snippet and detailed instructions) is mentioned only in this article:
https://wordpress.stackexchange.com/a/330933/38240

Unfortunately, to remove the trailing zeros with my plugin you will need to use code snippet:

/**
 * Use single-digit month number in permastructures
 * Use %monthnum2% or %daynum2% in "Permastructure" settings
 */
function pm_date_tags($default_uri, $post) {
	if(empty($post->post_type)) {
		return $default_uri;
	}

	if(strpos($default_uri, '%monthnum2%') !== false) {
		$monthnum = date('n', strtotime($post->post_date));
		$default_uri = str_replace('%monthnum2%', $monthnum, $default_uri);
	}
	
	if(strpos($default_uri, '%daynum2%') !== false) {
		$daynum = date('j', strtotime($post->post_date));
		$default_uri = str_replace('%daynum2%', $daynum, $default_uri);
	}

	return $default_uri;
}
add_filter('permalink_manager_filter_permastructure', 'pm_date_tags', 5, 2);

Please simply paste it to functions.php in your child theme directory. Then you will be able to use both %monthnum2% and %daynum2% in Permastructure settings.

Best regards,
Maciej
