Still getting heirachical taxonomy error

I am using WordPress 5.9 with the classic post editor. I am still getting the “More than 1 heirachical taxonomy detected… error.”

We are on version 2.7.3 of PublishPress Future.

I did see the fix posted about 4 months ago to solve this issue but the $defaults[‘taxonomy’] variable no longer exists in the /post-expirator/views/classic-metabox.php file. (https://www.ads-software.com/support/topic/category-based-expiration-not-working-for-custom-post-types-in-classic-editor/)

The changing category upon expiration feature would be extremely helpful in the maintenance of our site. I am so hoping that we can work together to fix the problem.

Thank you!
