A PHP Notice popped up

Thanks for the information. It seems I should fix it.

Could you let me know when it happens? Because it’s not what I expected, it’s important for me to know how you operate to generate this message.

I use your plugin together with the constant WP_POST_REVISIONS set to 5 in the wp-config.php file:
define( 'WP_POST_REVISIONS', 5 );

The PHP notice pops up only in the admin area when I change something in the menu (like the menu structure or the name of the menu items) in Appearance > Menu admin page. When I save the menu, this notice always pops up.

Well, okay right after I wrote my previous comment I realized there’s not too much sense to use this plugin together with the WP_POST_REVISIONS set to 5. So most likely it’s not a problem for other users.

I will investigate further details. Thanks for the information, anyway.

Thanks & have a nice day.

I get the PHP notice always on post-new.php, before a new post is created.

Thanks for the feedback.

I assume that the location is thin-out-revisions.php:824. But if you have different localtion, please let me know.
And do you have a WP_POST_REVISIONS configuration like Azalea Mollis?

Yes, I was talking about thin-out-revisions.php:824, which is the issue in this thread.

No, I have not WP_POST_REVISIONS configuration. Use the default WordPress revisions configuration.

The line thin-out-revisions.php:824 is:

$post_type_object = get_post_type_object( $parent ? get_post_type($parent) : $_POST['post_type'] );

The notice is triggered because in post-new.php, the index 'post_type' doesn’t exist in $_POST array.

I released a fixed version, 1.8.3. Thanks to all of you.

Great!! Thank you.
