Custom Post Type

What are your permalinks set to?

And what code did you use to make your CPTs?

Permalinks:-
Post name https://example.com/sample-post/
Code for CPTs:-
<?php
function create_post_type() {
register_post_type( ‘mysite_reviews’,
array(
‘labels’ => array(
‘name’ => __( ‘Reviews’ ),
‘singular_name’ => __( ‘Review’ )
),
‘public’ => true,
‘menu_position’ => 5,
‘rewrite’ => array(‘slug’ => ‘reviews’)
)
);
}
add_action( ‘init’, ‘create_post_type’ );
?>

This is set up using child of twenty twelve, on a 3.5 beta I upgraded today 9 10 2012.

It works on all permalinks as a draft but not as a published Post.
Does not work using Permalinks:-
Numeric https://example.com/archives/123
Post name https://example.com/sample-post/
 
Works as using Permalinks:-
Default https://example.com/?p=123
Day and name https://example.com/2012/10/08/sample-post/
Month and name https://example.com/2012/10/sample-post/

I hope this helps.

Sorry should have read:-

I tried your example code and I couldn’t reproduce your issue on 3.5 Beta 1/trunk. If you register a new post type and don’t visit and re-save Settings > Permalinks to flush the rules then most of the time you’ll get a 404. I’d suggest maybe try registering a different sample post type, flushing the rules and see if you can’t get past the 404’s.

Thanks for your reply,
Yes the Permalinks needed Flushing,
All fixed.

All fixed too, thanks ??
