URL rewrite problem in WordPress plugin

If you want a rewrite rule that loads a post type archive from a different URL, the simplest way is via an internal rewrite, which doesn’t get inserted into .htaccess. Internal rewrites map URLs to query arguments, and must result in a successful main query:

add_rewrite_rule(
    'some_url/?$',
    'index.php?post_type=yourcpt',
    'top'
);
