Breaks when updating Post or Page

The plugin works, but it gives an error whenever I update a post/page.

The error says:
—
Warning: Invalid argument supplied for foreach() in (hidden)/wp-content/plugins/post-access-controller/post-access-controller.php on line 396

Warning: Invalid argument supplied for foreach() in (hidden)/wp-content/plugins/post-access-controller/post-access-controller.php on line 402

When I see the errors, I go back to the previous page and refresh the post, I will see that my updates saved correctly, even with the errors.

I love the features of the plugin and it does exactly what I need it to do. I just have this issue that doesn’t look good for business when it comes to our team adding pages and posts.

Thanks for your hard work in making this great plugin.
