Custom Post Type with post type = 'post_type'

[displaynone]

When I create a CPT this way:

<?php
register_post_type( 'post_type', $args );

No posts, CPTs, ... are shown, but the posts count is correct

There's a long list of reserved terms in WordPress core, which can be found here: ​https://codex.wordpress.org/Reserved_Terms

There's a ticket for preventing post types with such names from being registered as well, see #31154.

Hi @displaynone, welcome to WordPress Trac! Thanks for the report.

As noted above, post_type is one of the reserved terms that cannot be used as an actual post type name.
