Error 404. Weird behavior with CPTs

Hi

I have a simple CPT called “test” created on functions.php:

$labels = array(
“name” => __( “Tests”, “fc-custom” ),
“singular_name” => __( “Test”, “fc-custom” ),
“menu_name” => “Tests”,
);
$args = array(
“label” => __( “Tests”, “fc-custom” ),
“labels” => $labels,
“description” => “”,
“public” => true,
“rewrite” => [ “slug” => “test-single”, “with_front” => false ],
“publicly_queryable” => true
);
register_post_type( “test”, $args );

I created a post titled “New test post” to test it which generates this permalink: https://dev.formulaclick.com/nemux/test-single/new-test-post/ but throws 404 error.

I have flushed permalinks updating wp-admin/options-permalink.php but still 404 remains. I’ve tried also flushing rules using a snippet but same result.

If I just install your plugin, without touching nothing… IT WORKS! But I can’t understand why. Permalink structure is the same on php code and in your plugin. I prefer using php code to manage permalink structure instead a plugin.

Do you have an idea what problem can I have on my database or something?

Thanks a lot!
