Balir-
Just as a fellow user, not the plugin developer… Please delete this “review” and move your issue into support where it belongs.
What you’re reporting is a PHP _Warning_ because you have WP_DEBUG turned on.
Leaving a 1 star “review” of a plugin with zero substance simply because of your hosting config is very bad form.

To reproduce. Install the plugin on a virgin install, immediately go to the “All Posts” page. Once ohe goes to the settings page and excludes an actual post type it fixes itself.
To fix for new installs:
/admin/settings.php:159
change:
‘id’ => ‘exclude_post_types’,
to:
‘id’ => array(‘exclude_post_types’),
