Aw, that is a bummer to waste both of our time. Thanks for seeing the issue though! I will add code to wp-config.php file and test again.

Wouldn’t the list be just as long with Allow? I would be adding a lot more IDs to the list: all the tags, all the categories, and the one taxonomy term in Curator Access taxonomy. I already tried adding the tax. term only, which hid all the categories and tags in WP post edit screen. Not cool!
