Plugin for WordPress that adds a notice in dashboard about WordPress automatically removing trashed posts after 30 days. Helpful for developers with lots of clients and sites with lots of editors.
It adds the notice to the message that appear when you trash an item and also shows the notice on the trashed post table. It works with all custom post types and pages as well. It also check if you have changed the number of days posts are deleted from trash.
I created this plugin after a client complained that she didn’t know that WordPress would automatically delete the post.
