Wordpress custom permalinks, pages are now 404

Question

I've set my permalinks to a custom structure:

/%menutype%/%postname%/

This works all right for my custom taxonomy (menutype) and anything that's an archive.

Now however, simple pages won't work, i.e.

index.php?page_id=32 -> 404!

OR

/about/ ->404

Here are my custom rewrite rules, 'menu' is my custom post, and 'menutype' is my custom taxonomy:

function custom_rewrite( $wp_rewrite ) {
    $feed_rules = array(
        'menu/[a-z]+/(.+)'    =>  'index.php?menu=' . $wp_rewrite->preg_index(1),
        'menu/([^/]+)(/[0-9]+)?/?$'    =>  'index.php?menutype=' . $wp_rewrite->preg_index(1),
        '/(.+)/'    =>  'index.php?page_id=' . $wp_rewrite->preg_index(1),

    );

        $wp_rewrite->rules = $feed_rules + $wp_rewrite->rules;
    }
    // refresh/flush permalinks in the dashboard if this is changed in any way
    add_filter( 'generate_rewrite_rules', 'custom_rewrite' );

You need to setup your permalinks for menutype using custom rewrite rules. What you've done is apply the menutype prefix to everything, even though menutype isn't relevant to everything, so things are being misinterpreted.

You would need something similar to this:

function custom_rewrite( $wp_rewrite ) {
    $feed_rules = array(
        '([^/]+)(/[0-9]+)?/?$'    =>  'index.php?menu_type='. $wp_rewrite->preg_index(1).'&post_name='. $wp_rewrite->preg_index(2)
    );

    $wp_rewrite->rules = $feed_rules + $wp_rewrite->rules;
}
// refresh/flush permalinks in the dashboard if this is changed in any way
add_filter( 'generate_rewrite_rules', 'custom_rewrite' );

However, I would recommend you add a prefix such as 'menus' etc beforehand to prevent further clashes with the existing rewrite rules.

Use the monkeyman rewrite analyser tool plugin to test any rewrite rules you make/change/edit by putting in URLs and seeing which rules are activated and in which order.
